Unit 2 MC Review

A T-Rex stomps on a turtle. Who puts the bigger force on who?

• Trex applies the bigger force

• Turtle applies the bigger force

• The turtle puts the same force on the trex that the trex puts on the turtle

• Since the trex is stepping on the turtle, only he puts a force on the turtle. The turtle does not put a force on him.

Wister slides a glass of chocolate milk across a bar top to Vause. There is no friction or any other force touching the chocolate milk. What is true?

• The chocolate milk will get faster and faster because no forces are on it to slow it down.

• The chocolate milk will get faster and faster because the force of Wister's hand is making it go faster even after he is no longer touching it.

• The chocolate milk will keep moving at a constant velocity.

• The chocolate milk will slow down until it stops before Vause touches it

Does this table support Newton's Second Law? (you should know why it does or does not).

• Yes

• No

• I honestly don't know (it's okay to pick this answer)

• You cannot determine the answer just from this picture.
