Question

mention five effects that force can produce give one example of each effect​

Answer 1

Answer:

Explanation:

1) A force can move a stationary object

Ex-The force of engine makes a stationery car to move.

2) A force can stop a moving object.

Ex-The force of brakes can stop a moving car.

3) A force can change the speed of a moving object.

Ex-When a hockey player hits a moving ball, the speed of ball increases.

4) A force can change the direction of a moving object: A force when  applied to a moving object can also change its direction. Example of such an effect of force is when a baseball player strikes a moving ball thrown at him; it changes its initial direction to a new direction.

5) A force can change the shape and size of an object: A force when  applied on an object can also change its shape and size. Example of such an effect of force is when we take a ball of dough and apply force to make different shapes and sizes of models out of it.

Answer 2

Answer:

Effects of Force

FORCE CHANGES DIRECTION OF MOTION - EXAMPLE

When a ball hits against a wall, it bounces back in the opposite direction. So the force exerted by the wall on the ball changes its direction of motion.

FORCE CHANGES SHAPE OF OBJECT - EXAMPLE

When a hammer strikes a hot rod, the rod bends. The force exerted by the hammer on the rod changes the shape of the rod.

EXAMPLES FOR EFFECT OF FORCE - EXAMPLE

Force may bring the following change:

1) Can change the state of an object(rest to motion/ motion to rest):For example, pushing a heavy stone in order to move it.

2) May change the speed of an object if it is already moving.For example,catching a ball hit by a batsman.

3) May change the direction of motion of an object.For example,footballer kicks a   moving ball to change its direction.

4) May bring about a change in the shape of an object.For example, blowing air in balloon.

5) May cause some or all of these effects.

FORCE CAN CHANGE THE DIRECTION OF AN OBJECT - EXAMPLE

A side wind can change the direction of a boat sailing in a sea.

FORCE CAN CHANGE THE SPEED OF AN OBJECT - EXAMPLE

Blowing wind or wind storm can change the speed of moving car.
