Explanation:
your answer
1) change in speed of moving objects. ex :- increasing the speed of a bicycle by exerting more force on the peddle.
2) it can make a stationary object move. ex:- pushing a box at rest on the table brings the box in motion.
3) change the direction of moving objects. ex:- pushing a cart to move in right direction.
▪️force can move a stationary object.
▪️A force can stop a moving object.
▪️A force can change the speed of a moving object.
▪️A force can change the direction of a moving ▪️object.
▪️ A force can change the shape and size of an object.
Examples for effect of force - example
Can change the state of an object(rest to motion/ motion to rest):For example, pushing a heavy stone in order to move it.
May change the speed of an object if it is already moving. ...
May change the direction of motion of an object.
A force can do one of four things to an object:
▪️Make it speed up - accelerate.
▪️Make it slow down - decelerate.
▪️Change its direction.
▪️Change its shape.
▪️force involves an interaction between two or more objects, and it causes a push or pull between the objects. ... Good examples of opposing force include drag due to interaction with an air mass and the force due to friction between two objects.
▪️Gravity.
♠️The weak force.
♠️Electromagnetism.
♠️The strong force.
- Change in speed of moving object. ex- increasing the speed of a bicycle by exerting more force on the peddle.
- Change the direction of moving object. ex-pushing a cart to move in in right direction.
- Change in shape and size.
