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 energy stored in an object based on its position, which is often based on gravity and expressed by the equation ______ = mgh.
What is potential energy (PE)?
It is the quantity symbolized by the letter "p" and which is a property of moving things.
What is momentum?
It is the initial momentum of a 40 kg block moving at 30 m/s?
What is 1200 kg*m/s ?
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 unit used to measure potential energy.
What is a Joule?
It is the unit for measurement of momentum.
What is kg*m/s ?
It is the length of time needed to stop a block experiencing a force of 60 N if it has an impulse of 1200 N*s?
What is 20 seconds?
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?
It is what happens when the height of an object above the ground doubles.
What is doubling of the potential energy?
It is equal to the change in the momentum of an object, or the force times the time.
What is impulse?
It is the type of collision for which kinetic energy is NOT conserved.
What is an inelastic collision?
The direction of displacement and the direction of the force applied are in the SAME DIRECTION. This means that 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 300 J?
It is the portion of an object's total mechanical energy that is not potential energy.
What is kinetic energy?
It is the type of collision for which system momentum is conserved.
What are both elastic and inelastic collisions?
It is the reason it makes sense that work and energy are both measured in Joules.
What is the interconversion of work and energy?
It is the amount of work done in the direction PERPENDICULAR to the direction of the force.
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 50 kg?
It is the energy that is gained by an object that is released and moves down a ramp without friction, as it loses potential energy.
What is Kinetic Energy?
Of these four expressions, it is the one that equals momentum.
a) impulse * velocity
b) force * distance
c) mass * velocity
d) force * velocity
What is mass * velocity ?
It is the new height of a box with a mass of 5.8 kg that is lifted from the garage floor and placed on a shelf if the box gains 145 J of Potential Energy (PE).
What is 2.5 m?
