Answer the brief. Discuss the effects of force briefly
Answers
Answer:
On a daily basis, we walk, we run, we play, we sit or stand. In all of these activities, we are changing the state of motion. We are bringing some object to rest or bringing it in motion. What is this called? What’re we actually doing? We’re actually applying ‘Force’ while bringing the object to rest or in motion. But what is a force? What are the effects of force? Let us scroll down and find out.
A ‘Force’ is a vector quantity that can be described as a push or pull on an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, the objects experience an equal and opposing force on each other. In other words both the objects ‘exert force’ on each other. Force only exists as a result of an interaction. If there is no interaction, the objects no longer experience the force. Force is measured in units called Newtons (N), named after the famous scientist Sir Issac Newton.
For force to exist, there must be an interaction between at least two objects. This interaction between the objects may or may not be physical. Pulling a rope or hitting a ball with a bat come physical interaction whereas forces like the magnetic force, electrostatic force, etc come under non-physical force.

A force has both magnitude and direction. The magnitude of the force expresses the strength of a force. To completely determine a force both direction and magnitude must be specified; since the direction or magnitude of the applied force changes its effects.

Answer:
FORCE: The push or a pull acting on the object is called force.
EFFECT OF FORCE :
- Force can set a stationary object in motion
Example: When force is applied on a stationary object, the object tends to move in the direction in which force is applied. For example, applying force on a stationary tennis ball will make it continue its motion in the direction of applied force.
- Force can stop down the moving object
Example: A moving toy car can be made to stop by applying a force. A bicycle can be stopped or slowed down by applying the brakes.
- Force can speed or slow down the moving object
Example: A stationary football can be made to move by giving it a small push (i.e., by kicking it). If we have an already moving toy car or ball, we can make it move faster by giving it a push in the direction in which it is moving. Thus, a force can make a stationary object move, and it can also make an already moving object move faster.
- Force is applied to change the direction of a moving object
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 can change the shape of an object by applying force
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
