Sports Science - Newtons Laws of Motion

What is Newtons first law of motion?

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

What is Newtons second law of motion?

Force equals mass times acceleration.

What is Newtons third law of motion?

For every action there is an equal and opposite reaction

What is the hippocampus?

The hippocampus is a part of the brain responsible for learning and forming new memories.

What is Inertia?

tendency of an object to resist changes in its velocity: whether in motion or motionless.

Define friction

Unbalanced force that acts on an object in motion

What are the four main types of friction?

Sliding friction: ice skating

Rolling friction: bowling

Fluid friction (air or liquid): air or water resistance

Static friction: initial friction when moving an object

What are the forms of unit fo the second law?

M = kg

A = m/s

Define Force

Push or pull that causes a change in the motion of an object

What are the forces called in the third law?

Action and reaction forces

Force is directly __ to acceleration
