100
A material that allows heat or electricity travel through easily
What is a conductor?
100
Motion is caused by friction.  (True/False)
False.  Friction is a force that resists motion.
100
What kind of energy is also called the energy of motion?

A. chemical   B. kinetic    C. potential    D. mechanical

B. kinetic
100
Compare gravity with gravitation.
Gravity comes from gravitation.  Gravity is the force acting on an object that pulls it towards the centre of a planet.  Gravitation on the other hand acts between two masses.
100
What will happen if the Earth stop rotating?
We will fly off to the space because of inertia.
200
A temporary magnet made from a piece of iron that is charged with electricity
What is electromagnet?
200
An object with a bigger mass accelerates slower than an object with a smaller mass.  (True/False)
True.  
200
What kind of energy is also called the energy of position?

A. chemical    B. kinetic   C. potential    D. motor

C. potential
200
Describe the components that made up a motor.
1) copper coil

2) electromagnet

3) permanent magnet

4) rod that spins in the centre

200
What will happen if the gravitation between the moon and the Earth disappears?
The moon will continue to fly in the space until it hits an object.
300
The change of speed or direction (or both) of a moving object
What is acceleration?
300
Scientists use the potential energy of the waterfall to generate hydroelectric power.  (True/False)
True.
300
Which kind of energy is useful below?

A. current electricity   B. static electricity   C. waste heat   D. pollution

A. current electricity
300
What tools do you need to compare the speed of two runners?
1)  stop watch

2)  measure a fixed distance with a meter stick

3)  cameras (at the Olympics)

300
If a person is riding a bicycle in a constant speed in circles, is this person accelerating?
Yes, because he/she is changing the direction of the movement of the bicycle.
400
Distance divided by time
What is speed?
400
The mass of an object changes depending of location, but weight doesn't.  (True/False)
False.  The weight of an object changes as the gravity changes.  
400
How do we describe the mass of an object?

A.  the volume capacity of an object

B.  the temperature of an object

C.  the amount of matter of an object in grams

D.  the weight of an object in newtons

C. the amount of matter of an object in grams
400
Compare a series circuit and a parallel circuit.
A series circuit only has one path for electricity to flow, whereas a parallel circuit has more than one path for electricity to flow.
400
Think of two ways that people use electromagnets to solve problems.
1) MRI machines in the hospitals

2) Picking up large pieces of metal in construction sites

3) Motors

4) Generators

500
A force that acts between two masses
What is gravitation?
500
The moon revolves around the Earth because of its inertia.  (True/False)
True.  The moon was attracted by the Earth and continues to move due to the inertia of its original motion.  
500
When a windsurfer rubs some wax onto a surfing board, what kind of force is he trying to create?

A. push   B. pull   C. gravity    D. friction

D. friction
500
John throws a basket ball towards the wall and it bounces back to him.  Which Newton law of motion is it related to?  
The third law of motion (action causes reaction)
500
If the size of the moon is one sixth of the Earth's, how will our weight change on the moon?
Our weight on the moon will be one sixth of our weight on Earth.
