1
Q
What is meant by displacement?
A
The displacement, S from a fixed point O is the distance measured from O in a specified direction.
2
Q
What is meant by speed?
A
Speed is the distance travelled per unit time
3
Q
What is meant by velocity?
A
Velocity is the rate of change of displacement
4
Q
What is meant by acceleration?
A
Acceleration is the rate of change of velocity
5
Q
What is meant by constant speed?
A
A body is said to be moving at constant speed if it covers equal distances in the same time intervals
6
Q
What is meant by uniform acceleration?
A
A body is said to be moving with uniform acceleration if its velocity changes by equal amounts in the same time intervals
