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?

Doing well on your IGCSE physics can often seem hard. You must put in an effort to do well and there aren’t too many shortcuts to get a good final grade – it requires work.

## How many topics are in Igcse physics?

The IGCSE Physics syllabus is divided into 8 units.

## 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.
