The acceleration of an object depends upon
a. its mass and volume.
b. its speed and direction.
c. its volume and the net force acting on it.
d. its mass and the net force acting upon it.

D) its mass and net force acting upon it.

Explanation:

Definition:

The acceleration is rate of change of velocity of an object with respect to time.

Formula:

a = Δv/Δt

a = acceleration

Δv = change in velocity

Δt = change in time

Units:

The unit of acceleration is m.s⁻².

Acceleration can also be determine through following formula,

F = m × a

a = F/m

In this case acceleration is depend upon mass and net force acting upon it.
