Force-Laws of Motion

Front

What is Newton's First Law?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

How long will an object remain at rest according to Newton's First Law of Motion?

Back

Until an unbalanced force occurs.

Front

What is the difference between mass and weight?

Back

Mass is how much matter is in an object, and weight is the gravitational pull on that object.

Front

What does Newton's Third Law state?

Back

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

Front

Calculate the net force on a 20 kg bike accelerating at 10 m/s².

Back

200 Newtons.

Front

What is the formula for calculating force?

Back

F = ma (Force = mass × acceleration).

Front

What is inertia?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.
