3
Q
What is acceleration ?
A
Acceleration is the rate at which velocity changes
4
Q
What is displacement?
A
Displacement is the change in position of an object
5
Q
What is average speed?
A
The average speed is calculated by diving the total distance travelled by the total time taken.
6
Q
What is instantaneous speed?
A
Instantaneous speed is the speed at the particular time
7
Q
What is uniform (linear) acceleration?
A
Uniform acceleration occurs when the change in velocity per second is always the same.
