What is a Wave?
A disturbance that carries energy from one location to another.
What is Energy?
Energy means the ability to do work.
What is a Force?
A force is a push or pull on an object.
What is Speed?
Speed is the distance an object travels per unit of time.
Momentum depends on mass and velocity. The more momentum, the harder it is to stop or change its direction.
True or False: A wave transports energy AND matter.
False. A wave only transports energy.
What is Potential Energy?
Potential energy is stored energy due to an object’s position--energy ready to go.
What is a Net Force?
The Net Force is the combination of all the forces acting on an object.
What is Velocity?
Velocity is the speed of an object in a particular direction.
What is the Law of Conservation of Momentum?
The Law of Conservation of Momentum states that the total amount of momentum DOES NOT change.
What is a Medium in a Wave?
A medium is a substance or material that carries the wave.
What is Kinetic Energy?
Kinetic energy is energy of motion.
What is Inertia?
Inertia is the tendency of all objects to resist any change in motion.
What is Acceleration?
Acceleration is the rate at which velocity changes.
Calculate the momentum of a 700g ball that is rolling down a ramp at 4.6m/s.
3.22 kg x m/s
What is a Transverse Wave?
A transverse wave has a medium that moves in a direction perpendicular to the direction that the wave moves.
What does the Law of Conservation of Energy State?
It states that the total amount of energy in a system remains constant or conserved.
What is the Difference between a Balanced and an Unbalanced Force?
Balanced forces are forces of equal magnitude but are opposite in direction. Unbalanced forces, on the other hand, are not equal in magnitude and may or may not be directed in the same direction.
What is Motion?
Motion is an objects change in position over time.
What is the Law of Conservation of Momentum?
The Law of Conservation of Momentum states that the total amount of momentum DOES NOT change.
What is a Longitudinal Wave?
A wave that has the motion of the medium parallel to the direction of the wave.
What are the 7 forms of Energy?
Mechanical, Chemical, Nuclear, Solar, Thermal (Heat), Electrical, Sound.
What does Newton's 1st Law State?
An object at rest remains at rest unless acted on by an unbalanced force. Furthermore, an object in motion remains in motion at a constant velocity unless acted on by an unbalanced force.
What does Newton's 2nd Law State?
Newton’s Second Law states that the net force is equal to the acceleration times the mass of the object (F=ma).
What does Newton's 3rd Law State?
Newton’s 3rd Law states that for every action, there is an equal and opposite reaction.
