Newton's Laws

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the definition of mass?

Back

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

Front

What is the definition of weight?

Back

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

Front

What is the normal force?

Back

The normal force is the perpendicular force exerted by a surface against an object resting on it.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces and their directions.

Front

What is the relationship between weight and mass?

Back

Weight is directly proportional to mass; as mass increases, weight increases, assuming constant gravitational acceleration.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two objects due to their masses.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that results in a change in the motion of an object, causing it to accelerate.

Front

What is inertia?

Back

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