Newton's Laws Pre-Assessment

Front

What is Newton's 1st Law of Motion?

Back

An object in motion will remain in motion, and an object at rest will remain at rest unless acted upon by a net external force.

Front

What does mass refer to in physics?

Back

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

Front

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

Back

The unit of force is the newton (N).

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's 2nd Law, force equals mass times acceleration (F=ma).

Front

What does it mean when we say an object has more mass?

Back

It means the object has more matter and therefore requires more force to accelerate compared to an object with less mass.

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.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

How does increasing force affect acceleration?

Back

Increasing the force applied to an object results in an increase in its acceleration, assuming mass remains constant.

Front

What is inertia?

Back

Inertia is 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 exerted by gravity on that mass.
