Fall Final Review

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of reactants equals the total mass of products.

Front

How do you calculate force?

Back

Force is calculated using the formula: Force = Mass × Acceleration (F = m × a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

If an object has a mass of 20 kg and accelerates at 10 m/s², what is the force applied?

Back

200 Newtons (using F = m × a).

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

When a constant force is applied, an increase in mass results in a decrease in acceleration, and vice versa.

Front

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

Back

The unit of force is the Newton (N).

Front

How many grams of chocolate powder are shown in the example of conservation of mass?

Back

15 g.

Front

Does the equation shown obey the law of conservation of mass?

Back

Yes.

Front

What happens to the total mass in a closed system during a chemical reaction?

Back

The total mass remains constant; it does not change.

Front

If four objects are struck with the same force, which will have the greatest acceleration?

Back

The object with the least mass will have the greatest acceleration.
