Question

A force does not change​

Answer 1

Answer:

it will change

Explanation:

it will change because of refractional force

an change in medium

and change in force applied

Answer 2

Energy does not change is:

• In physics, energy is a force that can change the movement of an object.
• Power can cause a heavy object to change its speed (e.g. from a resting place), that is, to accelerate.
• Power can also be accurately described as push or pull.
• A force that does not change the state of rest or movement of an object is a balanced force.
• So balanced energy does not allow the body to relax in order to move or to make the body move in order to ralax.

• It does not allow the body to move in any direction or to increase its speed.
• Energy can lead to subsequent changes in the state of physical activity.
• For example, if you are riding a bicycle and are moving, by stepping on it you are using your energy effectively to increase your speed.
• This is an example of the force used to accelerate or cause acceleration.
