Mid-Term Review

Front

What is the formula to calculate net force?

Back

F = ma (Force = mass x acceleration)

Front

If an object has a mass of 2 kg and accelerates at 4 m/s², what is the net force?

Back

8 N (Net Force = 2 kg x 4 m/s²)

Front

What does mass refer to in physics?

Back

The amount of matter in a substance.

Front

What does it mean to conserve mass?

Back

To keep it the same.

Front

What does pH measure?

Back

How acidic or basic a solution is.

Front

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

Back

Newton (N)

Front

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

Back

Force is directly proportional to mass and acceleration.

Front

What is the acceleration of an object if a net force of 10 N is applied to a mass of 2 kg?

Back

5 m/s² (Acceleration = Force / mass = 10 N / 2 kg)

Front

What happens to the net force if the mass of an object is doubled while keeping acceleration constant?

Back

The net force is doubled.

Front

What is the effect of increasing acceleration on net force, assuming mass remains constant?

Back

Net force increases.
