How do you find the weight of an object?

• Mass / Acceleration DTG

• Mass x Acceleration DTG

• Mass x Density

• Acceleration DTG / Mass

Pretend you are a famous space pioneer on a strict, constant space diet. As you travel from planet to planet, what is the one variable to never change?

• Your Mass

• Your weight

• The Acceleration DTG

The tendency of an object to resist a change in its motion is called _______

• Gravity

• Weight

• Mass

• Inertia

A feather and a bowling ball drop at the same rate on the moon (meaning they will hit the ground at the same time). Why is this?

• Voodoo Magic

• There is no air resistance on the moon (so no air friction)

• The force of gravity is less on the moon

• The force of gravity is greater on the moon

You are on a game show called ‘What Is That Moon?’, where you must correctly identify which moon you are on to win the grand prize. You are given a sheet with the acceleration DTG of 5 different moons in our solar system, and a weight scale. As you step on the scale, you read your weight as 71.4 N. You also know your mass to be 50 kg. Which moon are you on?

• Phobos

• Callisto

• Io

• Ganymede

• Titan
