Position and Motion
1. These 3 pieces of information are needed to describe your position
1. Reference point, distance, direction
4 A. A car that travels 300 miles in 3 hours is traveling at what speed?
4 A. 100 MPH
8. An object at rest stays at rest and and object in motion stays in motion unless acted upon by an outside force
10. This force opposes motion between two surfaces
15. This is a collision where objects will bounce off of another in opposite directions
15. Elastic Collision
2. Motion can be described as a change in this
4 B. A ball thrown at 100 M/S will take how long to travel 500 meters?
4 B. 5 seconds
9 A. How much force is needed to accelerate on object of 5kg by 20m/s^2
9 A. 100 N
11. What are two ways you could change the amount of friction between two surfaces?
11. Lubricants, and surface area
15. This is a collision where objects will stick together after a collision
15. Inelastic Collision
3. This is the fastest way to get from point A to B
Displacement
5. The difference between speed and velocity is this
9 B. A force of 50 N could accelerate an object of this mass at 10 m/s^2
9 B. 5 kg
12. What is the difference between balanced and unbalanced forces?
12. Balanced forces won't move, unbalanced forces will move or accelerate
20. What are two factors that affect the force of gravity between two objects?
20. Distance and Mass
3. This is the total traveled between two points
Distance
6. What are 3 ways you can change your velocity
14. For every action there is an equal and opposite reaction.
14. Newtons 3rd Law
13. Determine the net force. RIGHT: 50 N LEFT: 20 N
13. 30 N to the Right
21. What is the difference between Mass and Weight?
21. Mass is the amount of space and object takes up, weight is how heavy the object is (How much gravity pulls the object)
EXTRA FORCE CATEGORY: 18. What's the difference between contact and non-contact forces?
18. Contact require objects to touch, non-contact do not touch
7. What is the definition of acceleration
A rate of change of velocity or M/S^2
16. This is a force that pushes back on applied forces like Gravity
16. Normal Force
17. Why don't force pairs cancel each other out?
17. They act on different objects
