Chapter 2.1

Question 1

what is the formula for speed

Answer 1

distance travelled/timetaken

Question 2

what is the formula for average speed

Answer 2

total distance travelled/total time taken

Question 3

what is the si unit for speed

Answer 3

m/s

Question 4

what is uniform speed

Answer 4

Uniform (constant) speed is when the change in the distance travelled by an object per unit time is the same.

Question 5

what is velocity?

Answer 5

displacement/time taken

Question 6

what is acceleration

Answer 6

The rate of change of velocity

Question 7

What is the formula for acceleration

Answer 7

change of velocity/time taken

Question 8

what is uniform acceleration

Answer 8

An object undergoes uniform (constant) acceleration when the change in the velocity of the object per unit time is the same.

Question 9

what is the formula for uniform acceleration

Answer 9

acceleration(m/s^2)=final velocity(m/s) - initial velocity(m/s)/Time taken(s)

Question 10

what is non-uniform acceleration

Answer 10

An object undergoes non-uniform acceleration when the change in the velocity of the object per unit time is not the same.
