What type of motion is occurring when the slope of velocity vs time graph is not zero?
The type of motion occurring when the slope of a velocity vs. time graph is not zero is the object being measured was moved with an increasing/decreasing velocity away from/toward the sensor. That is to say, the object was speeding up or slowing down.
What type of motion can be occurring when the slope of a position time graph is constant?
Velocity is the slope of position vs. time. If that slope is not changing, the velocity is constant.
When the slope of a position vs time graph is zero?
In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing.
What does the slope of a velocity vs time graph tell you about the motion of an object?
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
What is this displacement?
Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position. For example- If an object moves from A position to B, then the object's position changes.
What is the slope of position vs time graph?
It was learned earlier in Lesson 3 that the slope of the line on a position versus time graph is equal to the velocity of the object.
What does slope of position time graph represent for a uniform motion?
The slope of the position-time graph indicates velocity.
Which describes what a velocity time graph would look like with no acceleration?
As discussed in the previous part of Lesson 4, the shape of a velocity versus time graph reveals pertinent information about an object's acceleration. For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero).
What is the physical meaning of the slope of the velocity versus time graph If the graph is a straight line?
time graph reveals pertinent information about an object's velocity. For example, a small slope means a small velocity; a negative slope means a negative velocity; a constant slope (straight line) means a constant velocity; a changing slope (curved line) means a changing velocity.
How do you describe motion on a velocity-time graph?
If an object moves along a straight line, its motion can be represented by a velocity-time (or speed-time) graph. The gradient of the line is equal to the acceleration of the object.
When can displacement be equal to zero?
Displacement can be zero even when distance is not zero. Consider two points A and B such that AB = 5 m. When a car travels from A to B and then back from B to A, distance = 5+5 = 10 m. Displacement = Minimum distance between final(B) and initial position(B) = 0.
What is non uniform motion?
Definition: This type of motion is defined as the motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.
When the slope of an object is negative it indicates that the object is moving blank?
time graph reveals pertinent information about an object's velocity. For example, a small slope means a small velocity; a negative slope means a negative velocity; a constant slope (straight line) means a constant velocity; a changing slope (curved line) means a changing velocity.
What is the slope undefined?
The slope of a line is undefined if the line is vertical. If you think of slope as rise over run, then the line rises an infinite amount, or goes straight up, but does not run at all.
What is uniform cellular motion?
The movement of a body following a circular path is called a circular motion. Now, the motion of a body moving with constant speed along a circular path is called Uniform Circular Motion.
Which graph represents an object with zero acceleration?
If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line). If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).
What does it mean if a velocity vs time graph shows a horizontal line?
On a velocity-time graph a horizontal (flat) line indicates the object is travelling at a constant speed. A straight diagonal line indicates the object's velocity is changing.
Which describes what a velocity-time graph would look like with no acceleration?
As discussed in the previous part of Lesson 4, the shape of a velocity versus time graph reveals pertinent information about an object's acceleration. For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero).
How do you describe a qualitative motion?
You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.
Can displacement be zero for a moving body?
Yes, In circular motion the total displacement after each cycle is zero.
Can a moving object ever have a displacement equal to zero?
Displacement is calculated on the basis of initial and final position. If initial and final position are same, displacement is zero. But distance is the total distance covered from initial to final position. So, it cannot be zero in this case.
What is uniform linear motion?
Uniform linear motion is uniform motion along a linear path or a straight line. The direction of motion is fixed. So, it is not accelerated. For e.g.: a car running with uniform speed of 10km/hr on a straight road.
Is circular motion uniform motion?
Movement of an object while rotating along a circular path is known as circular motion. Circular motion can be either uniform or non-uniform.
What does the slope of distance vs time graph represent?
A sloping line on a distance-time graph shows that the object is moving. In a distance-time graph, the slope or gradient of the line is equal to the speed of the object. The steeper the line (and the greater the gradient) the faster the object is moving.
When the slope of the displacement time graph is positive What does it indicates the object is moving?
(a) The slope of a displacement-time graph gives the velocity. If the slope is positive, it indicates that the body is moving away from the reference or the starting point. If the slope is negative, the body is reverting to the initial point.
What does a slope of 0 mean?
horizontal slope = 0. Note that when a line is horizontal the slope is 0. Undefined slope: slope = undefined. Note that when the line is vertical the slope is undefined.
What if the slope is a number over 0?
An undefined slope occurs when the slope is over 0 .
What is non-uniform motion?
Definition: This type of motion is defined as the motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.
When a body performs uniform circular motion the work done is zero?
Force in uniform circular motion is always perpendicular to the displacement and hence the angle between F and S is 900 always. After putting the value of θ. W=0. Hence, The work done in a uniform circular motion is always zero.
What is the shape of velocity time graph of an object moving with zero acceleration?
As discussed in the previous part of Lesson 4, the shape of a velocity versus time graph reveals pertinent information about an object's acceleration. For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero).
