Physical Science MCQ'S Class 8 FORCE

 FORCE

1.Force is a push or a pull.

2.A force can act on an object with or without being in contact with it.

3.A force acting

on body is either a contact force or force acting at a distance.

4.Field is a region in which an object, kept at a point in the region is influenced by it.

5. Friction is the force that opposes relative motion of surfaces in contact.

6.The force which we exert by using our body muscles is known as muscular force.

7.The attractive force between any two massive objects is called gravitational force.

8.The force exerted by a magnet on another magnet is called magnetic force. 

9.The magnetic force also acts on magnetic material such as iron.

10.The force exerted by a charged body on other charged or uncharged body is known

as electrostatic force.

11.Force has magnitude as well as direction.

12.The algebraic sum of all the forces acting on a body is known as net force, and is

denoted by Fnet.

13.A force can change the state of motion of an object.

14.Force may cause a change in the shape of an object.

15.The force acting on a unit area of a surface is called pressure.
