Work
It is the amount of force applied over a certain distance or (F x d).
What is work?
It is the kinetic energy equation.
What is K.E. = ½mv^2?
It is the equation for Gravitational Potential Energy
What is mgh?
It is the unit for momentum.
What is kg*m/s OR N*s?
It is the unit for Power.
What are Watts OR J/s?
This is the work done on an object being moved 3 meters by a 5 N force
What is 15 J?
It is what happens to kinetic energy when the mass is tripled and the velocity is the same.
What is tripling of the kinetic energy?
It is the PE of a 4 kg object lifted 5 meters.
What is 196.2 J?
It is the momentum of a 2 kg object moving at 3 m/s.
What is 6 kg*m/s?
It is the amount of power needed to do 60 J of work for 3 seconds.
What is 20 W?
It is another way to express the unit of Joules for work, relating it to the unit of force called newtons.
What is (newtons x meters), or newton-meters?
It is what happens to kinetic energy when the mass is the same but the velocity is doubled.
What is quadrupling of the kinetic energy?
When the height doubles, the potential energy of the object does this.
What is doubles?
It is the momentum of a 50 kg object traveling at 3.7 m/s.
What is 185 kg*m/s?
***DAILY DOUBLE***
20 W of power is enough to do 45 J of work for this amount of time.
What is 2.25 s?
***DAILY DOUBLE***
If a force is applied to an object, and the object moves in the same direction the force was applied, then work will have this value.
What is a positive value?
It is the amount of kinetic energy in a 3kg ball moving at 10 m/s.
What is 150 J?
A 40N object experiences 17 J of work. What height is it brought to?
What is 0.425 m?
A 3 kg object speeds up from 4 m/s to 7 m/s. What is the impulse the object experiences?
What is 9 kg*m/s?
A force of 5 N moving an object 7 m/s requires this much power.
What is 35 W?
A 50 N force is applied at an angle of 60 degrees and travels a horizontal distance of 24 m. What is the work done in the vertical direction?
What is 0 Joules?
This is the mass of a meteorite falling out of the sky with a velocity of 100m/s and possessing a kinetic energy of 500,000 J (500 kJ).
What is 100 kg?
It is the type of relationship that Gravitational Potential Energy and height have
What is linear/direct?
If a 23 N force is applied to an object at rest for 4 seconds, then this is the final momentum.
What is 92 kg*m/s?
A spring with a spring constant of 5 N/m is compressed 3 m. If the spring uses its PE to do work for 5 seconds, it had this much power.
What is 4.5 W?
