The difference between instantaneous speed and average speed. 

Instantaneous is at one moment in time and average is over a period of time. 

100

What is the formula for force. 

F=ma
100

Explain the difference between potential and kinetic energy 

Kinetic is in motion and potential is stored. 

100

The transfer of thermal energy is always from 

warmer to cooler
100

What is the top of the wave called

crest

100

What is an insulator

stops/slows current 

200

Formula for speed

S=D/T

200

What is the difference between an balanced force and a unbalanced force.

Unbalanced causes movement. 
200

Which of the following has kinetic energy? 

1. water flowing down a river

2. a bowling ball rolling down an alley

3. atoms inside a rock which is sitting on a cliff. 

all

200
Global wind patterns are a result of what? 

Convection currents. 

200

There are some waves that are close together in one system and some waves that are further apart in another. what is changing? 

Frequency is decreasing and wavelength is increasing

200
What is a conductor
sends current
300
Formula for Acceleration. HINT there are two
a=F/m or vf-vi/t
300
What is the relationship between mass and force

as mass increases force also increases. 

300

Explain at what point on a rollercoaster does the cart have the most potential energy 

The top of the first hill. 

300

The sun is what type of thermal energy

Radiation

300

What is the difference between longitudinal and transverse wave.

slinky and wave. 

300

An open circuit means

does not allow electricity to flow. 

400

Which is not accelerating? 

A. taking a curve at a constant speed

B. moving at a constant speed

A

400
A .8kg toy car is pushed with a force of 4N. What would the acceleration be? 

5 m/s2

400
Explain when a spring will have the most elastic potential energy 

When it is compressed. 

400
Touching a hot seat belt is what type of thermal energy transfer

Conduction

400

What is destructive interference

they cancel out

400

when a piece of glass is inserted into a simple circuit, the light bulb of the circuit does not light up. Under these conditions this would mean the glass is a 

insulator 

500

A bus traveling at 50 km/hr for 3.8 hours. The distances traveled will be- 

190 km

500
Describe the motions of a small car and a school bus that have an equal amount of force applied.

The car will have a greater acceleration than the bus. 

500

The mechanical energy of a system is equal to the kinetic energy plus the potential energy within the system. Explain why the total mechanical energy of a system remains constant in a frictionless environment. 

Due to the law of conservation, energy cannot be created nor destroyed. Energy will only change forms. 

500
if a light is shown in a mirror what will be the result 
It would reflect at the same angle
