What is force?

Back

Force is a push or pull on an object that can cause it to change its velocity (speed or direction).

What is mass?

Back

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

Front

How does mass affect force?

Back

The greater the mass of an object, the more force is required to change its motion (speed or direction).

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be a change in speed or direction.

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

What happens to an object when a force is applied?

Back

When a force is applied to an object, it can cause the object to start moving, stop moving, or change direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.

Front

What is the relationship between force and motion?

Back

Force is necessary to change the state of motion of an object; without force, an object at rest stays at rest, and an object in motion continues in motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
