Front

What law is best described by inertia?

Back

1st Law of Motion: 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 a force?

Back

A force is the PUSH or PULL on an object.

Front

What happens to an object's acceleration when it slows down, goes faster, or changes direction?

Back

Acceleration occurs when an object slows down, goes faster, or changes direction (turn).

Front

Which law of motion states that you must push or pull objects harder if they have more mass?

Back

2nd Law of Motion: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What does the 3rd Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.
