The Secret Formula
Spring into action
100
A quantity that measures the rate at which work is done or energy is transformed.
What is Power?
100
The property of an object or system that enables it to do work
What is energy?
100
The magnitude of the force times the magnitude of the displacement
What is Work?
100
net force x distance
What is the formula for work?
100
This is the unit for the spring constant
what is k?
200
Work divided by this equals power
What is time?
200
Energy associated with an object in motion
What is kinetic energy?
200
This defines the work kinetic energy theorem
What is the change in kinetic energy?
200
KE + ∑PE
What is the formula for mechanical energy?
200
a parameter that is a measure of a spring's resistance to being compressed or stretched
What is the spring constant?
300
This is the Si unit for power
What is a watt?
300
When energy is stored in any compressed or stretched object
What is elastic potential energy?
300
net force × displacement ×cosine of the angle between them
What is Net Work?
300
mgh
What is the formula for gravitational potential energy?
300
The spring constant is also known as this constant.
What is the force constant?
400
A watt is also equal to this
What is joule per second (J/s)?
400
Potential and kinetic are examples of this type of energy
What is mechanical energy?
400
These are the two ways in which work is measured
What is (N×m) and joules (J)?
400
1/2mv²
What is the formula for kinetic energy?
400
This is the unit in which the spring constant is measured.
what is N/m?
500
746 watts is equal to this
What is a horsepower?
500
The situation where in the absence of friction, the total mechanical energy remains the same
What is the conservation of mechanical energy?
500
The work done by the friction can be calculated by the change in mechanical energy. If there is no friction, then this is the change.
What is zero?
500
½kx²
What is the formula for elastic potential energy?
500
The law of physics that states that the force (F) needed to extend or compress a spring by some distance x scales linearly with respect to that distance
What is Hookes Law?
