Newtons 2nd Law
F=MxA
Newtons 3rd Law
Every action force has an equal and opposite reaction force.
Inertia
Tendency of an object to resist change in its motion
What is weight
The measure of the force of gravity acting on an object
What is Mass
The measure of the amount of matter in an object
How does weight and mass differ
Weight can change due to the force of gravity changing, mass will remain the same.
What is terminal velocity and how does an object reach terminal velocity?
The constant velocity of an object while falling towards the center of the Earth. An object reaches terminal velocity when the forces of gravity and air resistance become balanced.
