Question

1. What are the effects of a force acting on an object?
2. What types of forces are you familiar with?
3. What do you know about the gravitational force?​

Answer 1

1. When an force acts on an object then it changes :-

• The direction of it's motion
• Change in shape
• Change in velocity

2. The types of force are as follows:-

• Contact Force

- Muscular force

- Frictional Force

- Tension Force

- Normal Force

- Air Resistance Force

• Non - Contact Force

-Gravitational Force

-Electrical Force

-Magnetic Force

3. Gravitational force

Gravitational force is a type of non-contact force.

The force by which one object attracts another object.

Every object, including us is pulling on every other object in the entire universe.This phenomena is called Newton's Universal Law of Gravitation.

F =$\frac{Gm1m2}{r^2}$

Answer 2

Answer :-

Explanation :-

1) See the figure when force is acting on body it changes its position i.e., from rest to motion and Motion to rest.

or if equal forces are acting on same object in opposite directions no change would be observed.

2) Types of forces

See picture 2

1. Applied forces

2. Magnetic forces

3. drag forces

4. spring forces

5. gravitational force

And there are much more forces

3) Gravitational force

The force applied by earth on any object is called gravitational force.

see pic (3)

Fg = Gm1m2 / r²
