Question 2: True or False? A contact force does not need to touch the object that they push or pull.

Question 3: True or False? Gravity and Friction are two common action-at-a-distance forces.

Question 4: True or False? Mass is the amount of matter inside any given object, and does not change as a result of gravity.

Question 5: True or False? 9.8 N/kg is called Earth's gravitational field strength.
Question 6: True or False? The most common way to measure force is by using a Newton Spring Scale.


Weight vs Mass Practice Questions

1. Choose either the word "mass" or "weight" to correctly finish the sentence.
a) If gravity changes, the mass/weight of the object would change too. b) The mass/weight of an object would not change if the gravity changes. c) A newton (N) is the unit to measure mass/weight. d) A kilogram (kg) is the unit to measure mass/weight.


2. Calculate the weights of these masses if they were located on Earth.
a) 23 kg b) 65 kg c) 92 kg d) 174 kg
3. An object has a mass of 9.0 kg on the surface on the Moon. What would the object's:

a) Mass be on Earth? b) Force of Gravity on Earth?
