Q1. Explain 2-2 example for each condition that force can change the state of direction and shape of an object.
Answers
Explanation:
The effects of force on an object are as follows:
(1) A force can move a stationary object: A force applied on a stationary object can make it move. Example of such an effect of force is the force applied to lift a box from the floor.
(2) A force can stop a moving object: A force applied in the opposite direction of the movement of an object can stop a moving object. Example of such an effect of force is the force applied to catch a moving ball.
(3) A force can change the speed of a moving object: A force when applied on an object increases or decreases depending upon the strength and direction of the applied force. Example pushing of a moving swing harder in the direction of its swing will only increase its speed.
(4) A force can change the direction of a moving object: A force when applied to a moving object can also change its direction. Example of such an effect of force is when a baseball player strikes a moving ball thrown at him; it changes its initial direction to a new direction.
(5) A force can change the shape and size of an object: A force when applied on an object can also change its shape and size. Example of such an effect of force is when we take a ball of dough and apply force to make different shapes and sizes of models out of it.
Answer:
When two forces act in the same direction, they add together. ... Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
