Question

Explain the term acceleration.

Answer 1

The explanation for acceleration.

1. Acceleration can be defined as the rate of change of velocity with respect to time.
2. It is a vector quantity because it has the magnitude as well as direction.
3. It can also be expressed as the second derivative of position with respect to time.

Types of acceleration.

1. Uniform acceleration: When an object moves in a straight path with a uniform increase in velocity at equal intervals of time, it is said to be experiencing uniform acceleration.
2. Non-uniform acceleration: Non-uniform acceleration occurs when an object travels with an increase in velocity at unequal intervals of time.
3. Instantaneous acceleration: The acceleration of an object at any particular instant of time is known as instantaneous acceleration.

SI unit of acceleration:

1. The S.I unit for acceleration is a meter per second square or $\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s^2$}\right.$.
