P11 Motion in a Straight Line L-1

The rate of change of displacement is

The area under the velocity-time curve represents ___________ over a given interval of time.

Which is always true about the magnitudes of distance and displacement?

For a uniformly accelerated motion initial velocity is 10 \(ms^{-1}\). If acceleration = 1.5 \(ms^{-2}\). Find its velocity after 4 seconds.

What is a free fall?

A body is thrown upside. After sometime, it comes back to the earth. The direction of acceleration due to gravity ‘g‘ is

What is the stopping distance of a bike moving with a speed of v \(ms^{-1}\) and having a braking capacity (deceleration) \(ms^{-2}\)?

If the initial velocity of a car gets doubled, its stopping distance will become

Average speed is defined as 

The average speed of an object is _________ the magnitude of the average velocity over a given time interval.

Dimension of acceleration is
