Definitions
This is the unit that Work is measured in.
What is a Joule (J)/What are Joules (J)
If you increase the displacement of a person and its gravity/acceleration, what would happen to the work that person is exerting?
What is increases?
If you double an objects height, this happens to your Potential Energy.
What is doubling your Potential Energy?
This happens to power when you increase the amount of work done, the power ... (Increases? / Decreases?)
What is increases
This the rate at which work is done or Blank = Work/time
What is Power
This is the unit that power is measured in blank.
What is Watts
ALSO SOLVE THIS: If 54600 J of work is done on an object that causes it to accelerate at 0.594 m/s2 over 97.2 m, what is the mass of the object?
What is 946 kg?
An object moves down a ramp without friction. The object loses potential energy and gains this type of energy.
What is KE?
ALSO SOLVE THIS: How long would it take for a 198-W motor to perform 19200 J of work?
What is 97.0 s?
This is the amount of stored energy in an object based on it's height or Blank = m * g * h
What is Potential Energy (PE)
This is another way to express the unit Joules for work. (Work = Force * Distance, Joules = Blank * Blank)
What is Newton * Meters -- N*m
If 70100 J of work is necessary to lift an object by 442 m, what is the mass of the object?
How much power is needed to perform 1910 J of work for 9.59 s?
What is 199 W?
This is the amount of energy an object has while moving or Blank = 1/2*m*v^2
What is Kinetic Energy
This is the unit that PE is measured in.
What is Joules / J?
If 2440 J of work is applied to a 40.7-kg object, how fast is it moving now? (Use work as KE being transferred)
What is 10.9 m/s?
58200 J is required to lift an object 34.1 m above the ground. What is its mass?
What is 174 kg (X3 for choosing this one)
How high can a 150-W engine lift a 671-kg object in 6.93 s?
What is 0.158 m?
ALSO SOLVE THIS: 13300 J is required to lift an object 98.6 m above the ground. What is its mass?
What is 13.8 Kg
This is the unit that Kinetic Energy is measured in.
What is Joules / J? (X2 POINTS FOR CHOOSING THIS ONE)
An object is accelerated at 0.295 m/s2 over 93.9 m in 49.1 s by a 2.77-W engine. What is its mass?
4.91 kg
What is the mass of an object moving at 20.2 m/s if its kinetic energy is 1990 J?
What is 9.75 kg?
GREAT YOU EARN 500 POINTS FOR TRYING A HARD ONE WITH NO FEAR :)
What is GREAT?
