Mid-Term Review

Front

What is the formula to calculate net force?

Back

F = ma, where F is net force, m is mass, and a is 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 it mean to conserve mass?

Back

To keep it the same; mass cannot be created or destroyed.

Front

What does pH measure?

Back

How acidic or basic a solution is.

Front

What is mass?

Back

The amount of matter in a substance.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

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

If the mass of an object is doubled, what happens to the net force if the acceleration remains constant?

Back

The net force also doubles.

Front

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

Back

Net force increases.
