describe various effects of force on a body by illustrating examples from everyday life
Answers
Explanation:
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:
1. Force can change the shape of an object
for eg: 1. stretching of a rubber band
2. shape of dough can be changed by applying force.
2. Force can change the state of an object
for eg : 1. Kicking a football kept on the ground in rest position
2. A goalkeeper stopping the ball
3. Force can change the direction of an object
for eg: A badminton player changing the direction of the shuttle using the racket
4. Force can change the speed of a moving object
for eg: A cyclist can peddle slowly to decrease the speed of the cycle. He/She can peddle fast to increase the speed.
