# Force and acceleration

The ** force $$(F)$$** that acts on an object is equal to the product of its mass $$\Tblue{(m)}$$ and its acceleration $$\Tred{(a)}$$:

The object accelerates **in the direction of** the force applied on it.

Pushing a trolley in the forward direction causes the trolley to accelerate in the forward direction.

A **larger force** is required to accelerate a **larger mass** by the same amount. Similarly, a larger force is required to accelerate the same mass by a larger amount.

The force required to roll a boulder is larger than the force needed to roll a beach ball.

A ball dropped from a cliff would take longer to hit the bottom than the same ball thrown downwards.
