Question

C. ANSWER IN DETAIL:
1. i) Explain any three effects of force.
ii) Describe any two types of friction.​

Answer 1

Answer:

A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate.

There are two main types of friction, static friction and kinetic friction. Static friction operates between two surfaces that aren't moving relative to each other, while kinetic friction acts between objects in motion.

Answer 2

Answer:

i) The three effects of force are:-

1. Force can make a stationary object move or make a moving object move faster.
2. force can slow down or completely stop moving object.
3. force can change the direction of a moving object.

ii) The two types of friction are:-

1. Rolling friction
2. Fluid friction
