100

what is speed

speed is the measure of fast an object moves

100

define renewable energy

energy we can get more of in one human lifetime

100

forces change with the amount of energy true or false

true

100

speed is measured in m / s2 true or false

false its measured in m /s or km / h

100

 greenhouse gases are good true or false

false

200

what is an unbalanced force

a net force that is stronger on one side slowing or changing an objects speed

200

name 3 disadvantages of geothermal energy

high initial costs, greenhouse gases release during construction, risk of triggering earthquakes, geothermal reservoir may run out if not managed properly.

200

what are forces measured in

newtons / N

200

what is the formula for speed

speed = distance/time

200

what is Ms. Laurie's favorite NHL team (Im sorry whoever got this) 

the Ottawa senators

300

what are greenhouse gases

gases that trap heat from the sun causing global warming

300

name the 3 fossil fuels you have 7 seconds

oils gases and coal

300

what is a balanced force?

a net force of 0 on an object

300

what is the formula for acceleration

acceleration = final speed - starting speed / time

300

if acceleration is negative is it deceleration 

yes its deceleration

400

what is instantaneous speed

the speed of an object at one given moment

400

what is the most reliable energy source

fossil fuels oils and gases

400

If an object is moving and an unbalanced force starts acting on it what happens you have 10 seconds

it either speeds up or slows down and changes direction

400

a plane travels 5000km in 50 hours what's its speed

100km / h

400

name 2 renewable energy sources you have 5 seconds

solar , wind , tidal , wave , geothermal and nuclear

500

define clean energy in 15 seconds

energy that doesn't cause release of greenhouse gases

500

name 5 renewable energy sources you have 15 seconds

solar , wind , tidal , wave , geothermal and nuclear

500

a car has 5000 N pushing it forward an 4700N pushing it backwards what is the net force answer in 7 seconds

300 N to the left

500

A car moves changes speed from 50 m/s to 150 m/h in in 5 second what's its acceleration you have 1 minute seconds to solve this

20m / s2

500
a aircraft carrier travels 100km in 10h then a plane takes off and travels 500km in 20h what's the average speed?

20km / h
