Q1: if force acts on a body it will move in the direction in which the force acts. true/ false?

Q2: does a force acting on a body always cause a change in its state of motion?

1.  False. eg. When you are driving a bicycle and you apply the brakes. There is a stopping force applied in the direction opposite to the direction of motion of the bicycle. But, the bicycle still moves forward, doesn't it? So, the bicycle moves opposite to the direction of the applied force.

2. False. The net resultant force of all the forces determines the acceleration of the body. eg. When you push a wall, you apply force on it. Does it move? No!

A -1 It's true.....

A -2 Force not always change the state of motion....

1] false. when a force acts on a body, it does or doesnt move in the direction of the force applied. for ex if u push a ball leftwards, it wil move rightwards, but if u put a magnet near a piece of iron, it moves towards the magnet, thusmoving in the same direction

2] no, force usually causes 4 changes on the object on which force is applied. they are as follows

1. change in direction. ex when u push a ball rolling from the other way

2. change in shape. ex when u deform clay

3. change in speed. ex when u accelerate

4. chnge in state of motion. ex when u place an object from here tpo there
