Question

define force different type of force and its effect​

Answer 1

Answer:

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.

Explanation:

Interactive Nature of Force

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.

Addition and Subtraction of Forces

‘Net Force’ is the total force exerted.

For the block A, the net force acting is F1+F2 . The two forces are added since the force is exerted in the same direction.

And, for the block B, the net force acting is F1−F2. The two forces are subtracted since the forces are applied in opposite directions.

Effects of Force

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. When an object has several forces acting on it, the effects of force is same as one force acting on the object in a certain direction and this overall force is called the ‘resultant force’. The resultant force is essential to change the velocity of an object.

If the resultant force is zero the forces on the object are balanced.

If the resultant force acting on the object is ‘zero’ then: the object will remain stationary. In such a case the object will move at a steady speed in a straight line.

If the resultant force acting on the object isn’t zero then: the object will either accelerate or decelerate.

Answer 2

Hey... here's your answer.

Answer:

A force is an influence which tends to set a stationary body in or stop a moving body; or which tenda to change the speed and direction of a moving body ; or which tends to change the shape(and size) of a body.

Simple definition: A push or a pull on a body is called force.

Types of force:

• Balanced force
• Unbalanced force

Effects:

• It can change the shape and size of the body.
• It can move a stationary object.
• It can stop a moving object.
• It can change the direction of a moving object.
• It can change the speed of a moving object.
