What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is a force?

Back

A force is a push or pull on an object.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another object.

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 weight?

Back

Weight is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses.

Front

What is the net force?

Back

The net force is the vector sum of all the forces acting on an object.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant velocity.
