Chapter 2: Kinematics

Question 1

What is the difference between a scalar and a vector quantity?

Answer 1

Scalar quantities only have magnitude while vector quantities have both magnitude and direction

Question 2

What is distance?

Answer 2

Distance is the total length covered by a moving object along the path taken.

Question 3

What is displacement?

Answer 3

Displacement is the straight-line distance covered by a moving object, regardless of the path taken

Question 4

What is speed?

Answer 4

Speed is the distance moved per unit time.

Question 5

What is the formula for speed?

Answer 5

Speed=distance travelled/time taken

Question 6

What is velocity?

Answer 6

Velocity is the rate of change of displacement.

Question 7

What is the formula for velocity?

Answer 7

Velocity =displacement/time taken

Question 8

What is acceleration?

Answer 8

Acceleration is the rate of change of velocity.

Question 9

What is acceleration?

Answer 9

Acceleration is the rate of change of velocity.

Question 10

What is the formula for acceleratopm

Answer 10

Acceleration=Initial velocity-final velocity/time taken

Question 11

What is uniform acceleration?

Answer 11

Uniform acceleration is the constant rate of change of velocity.
