Question 1
1.

Use the image, and the vocabulary contained within, to explain how touch works.

Question 2
2.

Question 3
3.

Question 4

Question 5
5.

"Issac Newton's 1st Law of Motion states that an object's motion won't change unless acted upon by a force. If the object is moving, it will continue to move and if an object is still, it will remain still until acted on by a force."

Please describe an example from your investigations that supports Issac's 1st law. Back up your answer with detailed evidence.

Question 6
6.

"Isaac Newton's 2nd law of motion states that objects with more mass need a larger force to get them to move.

Please describe an example from your investigations that supports Issac's 2nd law. Back up your answer with detailed evidence.

Question 7
7.

"Isaac Newton's 3rd law states that for every action there is an equal and opposite reaction."

Please describe an example from your investigations that supports Issac's 3rd law. Back up your answer with detailed evidence.

Question 8
8.

Define elastic collision, provide and example from your studies.

Question 9
9.

Define plastic collision, provide an example from your studies.

Question 10
10.

There is at least one thing you learned, during our study of collisions, that was not covered in this assessment. Describe that one thing you learned. Be sure to provide details.

With constant mass, how does collision force change as speed increases?
The force increases with the increase in speed
The force remains unchanged with the increase in speed
The force decreases with the increase in speed
Speed has no impact
When speed is constant, how does increasing mass affect collision force?
Only time affects force
Force increases with mass
Force decreases with mass
Mass has no impact
Which scenario best shows rebound (bouncing back) in collision?
Bodies remain motionless after impact.
Cars merge after collision impacts.
Billiard balls collide and bounce off.
Objects heat up but do not bounce.
