gravitational potential energy- has potential to fall
31. When objects collide without being permanently deformed or without generating heat
- Energy is NOT lost; there is no damage to either object
32. - Ug to K
33. displacement: meter: m
Mass: Kilogram: Kg
Time: Seconds: s
velocity: meters per sec: m/s
acceleration: meters per sec squared: m/s2
Force: Newtons: N
Energy: Joule: J
Momentum: kg * m/s
Impulse: N*s
34. - elastic
-700 J
- less than 700 J
35. friction that acts on objects that are not moving
- resists motion
36. No, because acceleration is change in velocity
- only when your velocity or acceleration ir both is zero
37. - same force

38. Distance- the total distance traveled
Displacement- the shortest distance from point a to pint b?
39. Deals with both magnitude and direction
40. - momentum stays the same though a system, same in the beginning and end, unless outside forces
41. the tendency of an object to resist any change in its motion
- a law
42. The distance an object travels per unit of time
43. the amount of matter in an object
44. When colliding objects become entangled or coupled together, thereby generating heat or disfigurement
- Energy is lost during the collision (usually due to heat or friction); there is a change in shape
45. energy of motion
46. A push or pull exerted on an object
47. - same time, because same vertical speed
48. a mesurable extent of some kind
49. - when energy is lost, due to outside forces acting on it, work is done
50. - the acceleration goes down
51. - because of inertia
52. - actual stays the same
- apparent weigh gets smaller

gives magnitude only
can be both positive and negative
59. product of force and time interval during which the force acts.
- Impulse does NOT change in a collision; impulse is the change in momentum
