Forces and Newton's Laws

Front

What is the unit of measurement for weight?

Back

Newtons (N)

Front

What is the strength of gravity on Earth?

Back

Approximately 9.8 N/kg

Front

What fundamental force is responsible for the attraction or repulsion between charged objects?

Back

Electromagnetic Force

Front

What is the force that opposes the motion of an object sliding on a surface?

Back

Friction Force

Front

What is the force exerted by a surface to support the weight of an object resting on it?

Back

Normal Force

Front

According to Newton's Second Law, what is the relationship between force, mass, and acceleration?

Back

F = m * a (Force equals mass times acceleration)

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the difference between mass and weight?

Back

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

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.

Front

What is Newton's Third Law of Motion?

Back

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