Question

states and explain the terms: (a)=speed (b)velocity (c)acceleration?!!!!!​

Answer 1

Answer:

(a) Speed is the distance travelled per unit time.

The SI unit of speed is m/s.

(b) Velocity is the rate of change of displacement.

The SI unit of velocity is m/s.

(c) Acceleration is the rate of change of velocity.

The SI unit of acceleration is m/s^2 ( metre per second square).

Answer 2

Answer:

These are the physical quantities essential to studying the motion of an object.

Explanation:

(a) Speed is defined as the rate of change of distance. Speed is a scalar quantity. The unit of speed is m/s. The equation to find speed is:

Speed = Distance / Time

(b) Velocity is defined as the rate of change of displacement. Velocity is a vector quantity. The unit of velocity is m/s. The equation to find velocity is:

Velocity = Displacement / Time

(c) Acceleration is defined as the rate of change of velocity. Acceleration is a vector quantity. The unit of acceleration is m/s². The equation to find acceleration is:

Acceleration = Change in velocity / Time
