Front

What are the units for ACCELERATION?

Back

m/s²

Front

Newton's Third Law of Motion states that forces must always occur in ________.

Back

pairs

Front

What force slows objects down and keeps them from moving?

Back

Friction

Front

A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them. What law does this represent?

Back

Newton's 1st Law

Front

What is Newton's First Law of Motion?

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a)

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of objects, causing them to slow down or stop.
