Brennan is traveling in a car at a constant speed and in a constant direction. Once the brakes are applied , Brennan's upper body continues to move forward until a force in the opposite direction is applied on his body. Brennan's movement is an example of which scientific law? Group of answer choices Law of magnetism Law of Gravity Law of inertia Law of Conservation of Energy

The answer is law of inertia

Explanation:

The law of inertia is the first law in Newton's laws of motion. It postulates that an object or body at a state of rest or in uniform motion continue in such state unless an external force is applied.

Brennan is a body, in a car that is moving at a constatnt speed. The moment an external force (brakes) is applied to the car's speed, Brennan's upper body which was at a state of rest starts moving forward.

Likewise, it takes the application of another force (acceleration) to restore Brennan's upper body back to the state it was before the car's breakes were applied.
