Free body diagram (definition)

Front

a diagram showing all the forces acting on an object

Back

Acceleration

Front

The rate at which velocity changes (measured in m/s2)

Back

Newton's 3rd Law

Front

For every action there is an equal and opposite reaction

Back

Newton's 2nd Law Equation

Front

Force = mass x acceleration (F = ma)

Back

Net Force

Front

The sum of all forces acting on an object

Back

Friction equation

Front

Ff = μFn

Back

Force Normal

Front

force perpendicular to the surface (Fn)

Back

static friction

Front

Friction that acts on objects that are not moving

Back

kinetic friction

Front

Friction between moving surfaces

Back

Coefficient of Friction

Front

the ratio of the force of friction to the normal force acting between two objects (μ)

Back

Mass

Front

the amount of matter in an object (measured in kg)

Back

Newton's 1st Law

Front

(Law of Inertia) an object in motion tends to stay in motion & an object at rest stays at rest unless acted upon by an outside force.

Back

Newton

Front

SI unit of force (1 N = 1 kg*m/s2)

Back

Friction

Front

A force that opposes motion between two surfaces that are in contact
