Question 1 of 7
1. Question
A spring being pulled with 2.0 Newtons(N) of force stretches 5.0cm. How much force is required to stretch the spring to 4.0cm? (Express your answer as a decimal.)
 (1.6)N
Correct
Incorrect

Question 2 of 7
2. Question
A 16.0N force is applied to an object, causing it to move for a total distance of 3.0m. How many Joules of energy were transferred during the process?
 (48) Joules
Correct
Incorrect

Question 3 of 7
3. Question
An object is pushed until its kinetic energy increases by 15 Joules. If this kinetic energy resulted from a force of 9.0N over a distance of 3.0 meters, and no potential energy was gained by the object, then how many Joules of energy were converted to heat?
 (12) Joules
Correct
Incorrect

Question 4 of 7
4. Question
A 24N object is lifted 4.5 meters. How many Joules of potential energy were transferred to the object?
 (108) Joules
Correct
Incorrect

Question 5 of 7
5. Question
An object is pushed horizontally on a frictionless surface (that means no energy is converted to thermal or potential energy). How far was the object pushed if a force of 20N imparted 20 Joules of kinetic energy into it? (Include units in your answer.)
Correct
Incorrect

Question 6 of 7
6. Question
How many Joules of work are done to a stationary brick wall that has a force of 100N applied to it for 9 seconds?
 (0) Joules
Correct
Incorrect

Question 7 of 7
7. Question
Electrical energy can be converted to heat in an electric stove. A motor can convert electrical energy into potential energy if a pulley is attached to the motor and a cord is attached to the pulley. How high can a 25 Watt motor lift a 100 Newton weight in one minute? Assume all of the energy from the motor is used to lift the weight. None is converted to heat or kinetic energy.
 (15) meters
Correct
Incorrect
