write down the effects force ?
Answers
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. When there's the interaction between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction.
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.
