Answer: Velocity
3. the rate at which velocity changes.
Answer: Acceleration
4. An object accelerates if:
Answer:
It speeds up
It slows down
It changes direction
5. An object slowing down =
Answer: negative acceleration.
6. Is deceleration written as a positive or negative number?
Answer: Negative
7. final speed-initial speed/time
Answer: formula for acceleration
8. m/s2 or km/hr2
Answer: units for acceleration
9. Time is in acceleration
Answer: squared
,10. A flat horizontal slope indicates...
Answer: constant speed
11. If speed is constant what is acceleration?
Answer: 0
12. A downward slope =
Answer: object slowing down
13. An object at rest will remain at rest and an object in motion will remain in
motion unless acted upon by an outside/unbalanced force.
Answer: Newton's First Law of Motion
14. resistance to a change in motion. It relates directly to an object's mass.
Answer: - Inertia
15. Newton's 1st law is referred to as...
Answer: Law of Inertia.
16. The size and direction of a net force equals the mass times the acceleration.
Answer: Newton's Second Law of Motion
17. Net force = mass x acceleration
Answer: Newton's Second Law
18. Force = Newtons Mass = kilograms
Acceleration = m/s2 or km/hr2
Answer: Units for Newton's Second Law
19. For every action, there is an equal and opposite reaction.
Answer: Newton's Third Law of Motion
20. :When you walk, your feet push off of the ground, but the ground exerts an equal
and opposite force on your feet.: Newton's Third Law of Motion:
21. the force that 2 surfaces exert on each other when they rub together.
Answer: Friction
22. Two factors that affect friction:
Answer: The type of surface How hard the two surfaces are pushed together.
, 23. A rough surface means friction
Answer: more friction
24. When is an object in motion?
Answer: An object is in motion if its position changes when compared to another
object.
25. the place or object used for comparison to determine whether something is
inmotion.
Answer: Reference point
26. A push or a pull
Answer: force
27. What is force described by?
Answer: strength and direction
28. Measured in Newtons (N).
Answer: force/weight
29. the type of force that is applied when one object actually touches another object
Answer: Contact force
30. Ex: Friction
Answer: Contact force
31. the force that 2 objects apply to each other when they rub against each other
Answer: Contact force
32. a force applied to an object whether it touches the object or not.
Answer: Noncontact force
33. Ex: Gravity/magnetism
Answer: Noncontact force
34. a force that pulls objects toward each other as a result of their masses.
Answer: - Gravity
35. when two forces acting on an object are equal in strength & in opposite
directions.
