Physics Quiz

How can you apply force to an object? Give an example.

• By measuring the object

• By heating the object

• By pushing or pulling the object

• By observing the object

Describe the difference between mass and weight.

• Mass is a force measured in newtons and weight is always the same.

• Mass is measured in kilograms and weight is a force that depends on mass and gravity.

• Weight is measured in kilograms and mass is a force that depends on gravity.

• Mass and weight are both measured in newtons and do not depend on gravity.
