6th Science Unit 5 Energy, Motion and Forces Review

What describes the location of an object?

• reference point

• position

• energy

• speed

What is the law of conservation of energy?

• the amount of kinetic energy is constant in an object

• energy cannot be created or destroyed

• an object can have kinetic or potential energy but not both

• the energy an object creates is equal to the energy it destroys

A weather station reports the wind is blowing northeast at 12 km/h. Why is northeast at 12 km/h a vector?

• The speed in km/h

• The speed is constant

• Speed and direction are given

How does gravity make it easier to hammer a nail into a board?

• Gravity pushes the board up helping the nail go in

• Gravity pulls the board and nail towards each other

• Gravity pulls the hammer down so it pushes the nail

• Gravity pulls the nail down but doesn't act on the hammer
