Equations
What is Newton's second law of motion?
F=MA
What is friction?
A force that opposes Applied force.
What energy provides motion?
Kinetic Energy is the energy of this process
What is Potential Energy?
A form of energy in which the main source of power is stored until use.
What are Newton's 3 laws of motion?
An object remains at rest unless there is an extreme force, force=mass times acceleration, and for every action, there is an equal and opposite reaction.
What is the equation of Velocity?
V=m/s
What causes friction?
Two or more objects rubbing against each other
What is Total Energy?
Kinetic energy+potential energy
What are joules?
The unit that potential energy is measured in.
What is force?
A kind of push or pull on an object.
What is the equation of the normal reaction force?
Ff=UR
What contributes to friction?
Weight, Applied Force, Surface, and Normal reaction force
What is Temperature?
The measure of the average Kinetic Energy within a substance
What is gravitational potential energy?
The potential energy that exists between two objects that put a certain pull on each other.
What is displacement divided by time?
The formula for velocity.
What is the equation of coefficient of friction?
U=Ff/R
Name 6 Ways Friction helps us.
Walking, Creating heat, etc.
The loss of Kinetic Energy results in
The opposition of motion by friction must be transferred in some way or another
What is Elastic potential energy?
The potential energy that exerts force when released from a point of compression or stretching.
What is acceleration?
A change in velocity.
What is the equation of potential energy?
PE=mgh
What happens when there is a greater amount of friction / rougher surface?
The greater the coefficient of friction becomes.
Fill in the Blank :
As kinetic energy in a substance increases, ______
The molecules begin to move more rapidly generating heat
What is Newton’s cradle?
Potential energy is shown in this invention by Isaac Newton where a set of balls transfer energy to each other.
What is negative acceleration?
What is negative acceleration?For example, A car’s brake is slammed causing it to stop and the driver to lunge forward.
