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 at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second 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 friction?

Back

Friction is a force that opposes the motion of an object in contact with a surface.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted on that mass by gravity.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object.

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.
