Exit Check 3.2 - Force of Gavity

3.2.1

A measure of how much matter (particles) an object has is--

• weight

• gravity

• mass

• volume

Answer explanation

This question links to success criteria 3.2.1: I can differentiate between mass and weight.

If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.

3.2.1

What is the definition of "weight"?

• measure of the gravitation pull on an object

• the time it takes to get on a ride

• the amount of matter in an object

• the size of an object

Answer explanation

3.2.1

Why would you weigh less on the moon compared to Earth?

• The moon has no air, so no air is pushing down on you.

• The moon has more sun, so sunlight Pulls up on you more

• The moon has less mass, so gravity pulls on you more

• The moon has less mass, so gravity pulls on you less.

3.2.2

Two objects of the same shape and different masses are set to be dropped on the moon. Which of the following statements is correct.

• The heavier object will land first but both objects will land with the same force

• Both objects will land at the same time and the lighter object will land with more force

• Both objects will land at the same time and the heavier object will land with more force.

• The heavier object will land first and the heavier object will land with more force.

Answer explanation

This question links to success criteria 3.2.2: I can explain and calculate the relationship between force of gravity, mass and acceleration due to gravity.

If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.
