Mid-Term Review

Front

What is mass?

Back

Mass is the amount of matter in a substance.

Front

What does it mean to conserve mass?

Back

To conserve mass means to keep it the same.

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 (calculated as 2 kg x 4 m/s²).

Front

What does pH measure?

Back

pH measures how acidic or basic a solution is.

Front

How do you calculate net force if mass is 2 kg and acceleration is 4 m/s²?

Back

Net force is calculated as 2 kg x 4 m/s².

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

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 mass, acceleration, and force?

Back

The relationship is defined by Newton's second law of motion: F = ma.

Front

What happens to the net force if mass increases while acceleration remains constant?

Back

The net force increases.
