26. True or False. There are three ways that electricity can be transferred.

27. True or False. There are three ways that electricity can be transferred.
Induction- production of an electromotive force or voltage across an electrical conductor due to its dynamic interaction with a magnetic field
Conduction-  process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove. The fire's heat causes molecules in the pan to vibrate faster, making it hotter.
Friction-  the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

53. The rate at which an object moves is called
Speed
Momentum
Velocity
Acceleration

54. The rate at which an object moves is called
Speed
Momentum- the strength or force that something has when it is moving. : the strength or force that allows something to continue or to grow stronger or faster as time passes
Velocity-the speed of something in a given direction
Acceleration- A change in the velocity of an object. Note: The most familiar kind ofacceleration is a change in the speed of an object. An object that stays at the same speed but changes direction, however, is also being accelerated.

55. State the first law of motion (Newton’s first law)

56. State the first law of motion (Newton’s first law)
Every object in a state of rest or uniform motion remains in that state unless an external force is applied to it. This is called inertia.

57. State Newton’s second law of motion.

58. State Newton’s second law of motion.
F= ma
Force = mass X acceleration
This describes the relationship between an object’s mass and the amount of force needed to accelerate the object.
