# What is force in physics Igcse?

A force causes an object to undergo a specific change. Unbalanced forces cause changes in speed, shape or direction. Gravitational forces act between masses. Friction opposes motion.

## Is physics hard in Igcse?

## What equations are given in Igcse physics exam?

• average speed= distance moved. time taken. v= s. t. average speed. = distance moved. time taken. v. = s. t.
• acceleration= change in velocity. time taken. a= (v − u) t. acceleration. = change in velocity. time taken. a. = (v – u)
• force. = mass × acceleration. F= m × a.
• weight. = mass × gravitational field strength. W= m × g.
