Question

list the effect of force explaining each one briefly​

Answer 1

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 the 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

Answer:

The push or pull experienced by an object with the mass that causes to change the velocity is called force. Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction

The quantity of force is expressed by the product of mass (m) and acceleration (a). Mathematically the equation can be written as

F = ma

Where,

F= Force

m = mass

a = acceleration

When a force acts on an object the objects the objects have different effects of force. So let us know about the effects of force on an object.

Force can set a stationary object in motion:

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 either stop or slow down the moving object:

Force needs to be applied on a moving object either to stop it or to slow down the object. For example, the moving ball can be stopped by applying external force.

Force is applied to change the direction of moving object:

The direction of a moving object can be changed by applying the force on that object. For example, the direction of the moving football can be changed by applying force at an angle such that the direction is changed.

The shape of an object can be changed by applying force:

Consider a rod which is circular in shape, by hammering the rod which is applying an external force, the rod can be turned into a flat sheet.
