Unit 3: Forces and Newton's Laws of Motion

Front

What is Newton's 2nd law of motion?

Back

Force = Mass multiplied by acceleration.

Front

If a force of 26 N is exerted on two soccer balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?

Back

The one with a mass of 0.52 kg will have the greatest acceleration.

Front

What is Newton's First Law known as?

Back

Inertia.

Front

Friction is a force that acts against the motion of objects. True or False?

Back

True.

Front

What is the formula for force?

Back

F = M * A.

Front

What does inertia refer to in Newton's First Law?

Back

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

Front

What is the relationship between mass and acceleration in Newton's 2nd law?

Back

Acceleration is inversely proportional to mass when force is constant.

Front

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

Back

Newton (N).

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of objects, causing them to slow down or stop.

Front

How does increasing mass affect acceleration when force is constant?

Back

Increasing mass decreases acceleration.
