Kinematics Chapter 2

Question 1

What is the formula for speed

Answer 1

Speed = distance/time

Question 2

What is uniform speed?

Answer 2

Uniform speed Is the change in the distance travelled by an object for every unit of Time is the same./ constant speed

Question 3

What is distance?

Answer 3

Distance is the total length covered by a moving object regardless of the direction of motion.

Question 4

What is displacement?

Answer 4

Displacement is the distance measured in straight line from the starting point to the ending point.

Question 5

What is the formula of velocity?

Answer 5

Total displacement/ total time

Question 6

What is acceleration?

Answer 6

Acceleration is rate of change of velocity.

Question 7

What is the formula of acceleration

Answer 7

Acceleration = change in velocity/time taken

Question 8

What is uniform acceleration?

Answer 8

Uniform acceleration is a constant rate of change of velocity./ constant acceleration.
