mention five effects that force can produce give one example of each effect
Answers
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:
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.
