What is velocity graph Mcq?

Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. They can be used to show acceleration and to work out displacement. Physics.

What does a horizontal line on a velocity time graph represent Quizizz?

What does a flat (horizontal) line on a velocity-time graph mean? The object is not moving. The object is moving, but at a constant velocity.

How can you determine acceleration from a velocity-time graph?

Acceleration can be calculated by dividing the change in velocity (measured in metres per second) by the time taken for the change (in seconds). The units of acceleration are m/s/s or m/s 2.

What does the slope of a velocity time graph gives?

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 does the slope of speed-time graph indicate?

Speed-time graphs A sloping line on a speed-time graph represents an acceleration . The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down. If the line slopes upward from left to right, this means the object is speeding up.

What does a velocity-time graph look like?

If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive). If the acceleration is negative, then the velocity-time graph is a downward sloping line (i.e., the slope is negative). If the acceleration is great, then the line slopes up steeply (i.e., the slope is great).

How many types of velocity-time graphs are there?

The shapes of the velocity vs. time graphs for these two basic types of motion – constant velocity motion and accelerated motion (i.e., changing velocity) – reveal an important principle.
