Physics forces

What is a force

A push or pull

What units does force use

Newtons or N

What is a new force

The total force acting on an object

What is friction

Friction is a force that opposes or slows down motion

What is an Equilibrium

When the total force and Velocity is at 0 or moving at constant velocity

What could be another example of an equilibrium

Terminal velocity

What is the difference between mass and weights

Mass is the amount of matter while weight is force due to gravity

What is newton’s 1 law

The law on inertia: the property of matter to resist change in motion

What is another definition of Newton’s first law

An object at rest remains at rest and an object in motion says in motion unless acted apon by outside forces

If two objects have the same amount of force and different weights what will happen

The bigger one will slow down and the smaller one will get faster

What is newtons 2 law

F=MxA

What equation do you use to find weight

W= MxG

Force and mass are

Direct

Force and acceleration are

Directly

Mass and acceleration are

Inversely

What is Newton’s 3 law

For every action there is an equal and opposite reaction

If an object is at rest, are there any forces acting upon it?

Yes

If you divide Force by acceleration, what UNIT do you get?

Kg

Which of the following is NOT a unit for weight?

Kg

If you divide Force by mass, what VARIABLE do you get?

M/S2

When an object hits terminal velocity, the force upward due to air resistance equals the force downward due to

Weight
