The kilowatt-hour used on electricity bills is a unit used to measure this
What is energy?
300
According to the graph shown, the 117 kg object's kinetic energy changed by this much from 1 to 3 seconds.
What is - 46,800 J?
300
Doubling the height of an object will cause the gravitational potential energy to increase by this factor
What is 2?
300
A 16 kg cart had 225 J of work done on it by the tension force, but the force of friction did -153 J, so the cart's final speed was this.
What is 3.0 m/s?
300
This is the conservation of energy equation for the cart shown in the diagram; the cart comes to rest at point B.
What is

A 60 watt lightbulb uses this many joules of energy each minute
What is 3600 joules?
400
In the graph shown, the object's kinetic energy changes by this much between 0 and 20 seconds.
What is 0 J?
400
The velocity vs time graph shown is created from a roller coaster moving along the track, showing that the roller coasters gravitational potential energy was at a maximum at this time
What is 70 seconds?
400
According to this force vs time graph, this is the amount of work done between 25 and 75 seconds.
What is 0 joules?

A 1000 kg car's engine accelerates the car and the velocity vs time graph shown is created, which shows a power output of this many watts between 3 and 7 seconds.
What is 1500 W?
500
According to the graph shown, the object's kinetic energy increased the most during this second.
What is from 4 - 5 seconds?
500
A person stretches a very large spring by a distance of 7 cm, then they stretch the same spring a distance of 49 cm. If they stored 49 J in the spring when it was stretched 7 cm, they must have stored this must energy in the spring when it was stretched to 49 cm.
What is 2401 J?
500
A frictionless cart experiences the net force shown in this graph and ends up with a speed of 6 m/s, so this must be the mass of the cart.
