Front

What is Mass?

Back

The amount of matter in an object, usually measured in kilograms or grams.

Front

What is Velocity?

Back

The speed of an object in a specific direction.

Front

What is Acceleration?

Back

The rate at which an object changes its velocity, which can be a change in speed or direction.

Front

What is Friction?

Back

A force that opposes the motion of an object, often caused by contact with another surface.

Front

What is the relationship between mass and force?

Back

According to Newton's second law, force equals mass times acceleration (F = ma). More mass requires more force to accelerate.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion; more massive objects have more inertia.

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.
