W= 125 J

d = 10 m

F = ???

P=25 watts

W=5000 Joules

t=???

If 68 W of power is produced in 18 seconds, how much work is done?

How much work is produced when 350 N is used to move a car 5 m?

W = 500 Joules

t = 25 seconds

P = ???

If 68 Joules were necessary to move a 4 Newton crate, how far was the crate moved?

How much work is done in holding a 15 N sack of potatoes while waiting in line at the grocery store for 3 minutes?

How much time is needed to produce 720 Joules of work if 90 watts of power is used?

If a group of workers can apply a force of 1,000 Newtons to move a crate 20 meters, what amount of work will they have accomplished?

What is the unit of measurement for kinetic energy

Kinetic energy can be calculated using the formula

KE = 1/2mv2. What is the kinetic energy of a bicycle that has a mass of 20 kg and is traveling at a velocity of 10 m/sec?

The formula for calculating potential energy is

Figure the PE.

mass= 3 kg

gravity= 9.8m/s2

height= 40m

Solve

PE= 52 J

mass= ?

gravity= 9.8 m/s2

height= 18 m

Solve for h.

PE= 74 J

mass= 3.8 kg

gravity= 9.8 m/s2

height= ?

Find the mass of a car that is traveling at a velocity of 60 m/s North. The car has 5,040,000 J of kinetic energy.

Calculate the potential energy of a rock with a mass of 55 kg while sitting on a cliff that is 27 m high

An automobile is sitting on a hill which is 20 m higher than ground level. Find the mass of the automobile if it contains 362,600 J of potential energy.
