Chapter 3 - Motion and Force - 5


Physics Class 11
1. Displacement is defined as the change in the position of a body from its initial position to its final position.


2. The slope of displacement time graph gives acceleration of a moving body.


3. If the body is moving with uniform acceleration then its slope is zero.


4. Velocity time graphs only gives information about the acceleration of a moving body.


5. If a body is moving with variable velocity, then its average and instantaneous velocities are also equal.


6. A body dropped from a 100m high tower will strike the earth with the velocity of 100 m/s.


7. The average value of gravity near the earth's surface is 9.8 ms-2.


8. Mass is the qualitative measure of inertia.
