200

The formula for work

What is force x distance?

200

The formula for power

What is work / time?

300

It's what happens to the distance a spring is stretched if you double the force on it

What is it doubles?

300

It's the amount of potential energy when a 30 N/m spring is stretched 0.5 m.

What is 3.75 J

300

The kind of energy that a baseball has when it has been thrown in the air and it has just reached it's maximum height.

What is gravitational potential?

300
It's how much work is done when you push a box 3.0 m with 20 N of force.

What is 60 J?

300
A 60 watt bulb runs for 5 seconds. How much energy does it use??
What is 300 J
400

It is the spring constant of a spring that stretches 50 cm when a 20N force is applied to it.

What is 40 N/m?

400

A compressed spring has a potential energy of 18 J. If the spring constant of the spring is 400 N/m, it's the distance by which the spring is compressed.

What is 0.3 m?

400

It's how fast an 2 kg object would move if it was released from a spring with 25 J of potential energy.

What is 5 m/s?

400

It's how much work is done when a 10 kg mass is lifted 5.0 m.

What is 490 J

400
You push down on a 30 N box for 10 minutes. how much power is used??
What is 0 W
500

It is the mass that will stretch a 24.5N/m spring 10 cm when it is hung from the spring.

What is 0.25 kg?

500

It's the one which has more spring potential energy: a 20 N/m spring stretched 10 cm, or a 10 N/m spring stretched 20 cm.

What the 10 N/m spring?

500

It's how high a 1 kg rock would go if it was released from a sling shot that has 25 J of spring potential energy.

What is 2.6 m

500
It's the amount of work done to accelerate a 1000 kg car from rest to a speed of 20 m/s.


Hint: What is the change of energy of the car?

What is 20,000 J?
