Answer» ong>Answer: * 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. * 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. * Can change the state of an object(REST to motion/ motion to rest):For example, pushing a heavy stone in order to move it. * May change the speed of an object if it is already moving.For example,catching a ball hit by a batsman. * May change the direction of motion of an object.For example,footballer kicks a moving ball to change its direction. * May bring about a change in the shape of an object.For example, blowing air in balloon. * 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. hope this will be HELPFUL to you.please follow me only if u like |
