Forces and Motion
This is a change in velocity over time.
Acceleration
This is the ability to do work.
Energy
This when light waves bend or spread out.
Diffraction
This is when two or more objects crash into each other by force.
Collision
These are particles that make up light.
Photons
This is the speed and direction of an object.
Velocity
This is energy that is stored in an object.
Potential energy.
This law states that objects will pull on each other, and the larger object will have the stronger gravitational force.
Law of Universal Gravitation
This is a law that states that in a closed system, energy cannot be created or destroyed but can be transformed from one type to another.
Conservation of energy.
These are disturbances in space-time caused by accelerated masses.
Gravitational waves.
What is the difference between contact and non contact forces?
Contact forces involve a physical object touching another. Non contact forces do not. An example of a non contact force would be gravity.
This is energy an object has because it is moving.
Kinetic energy.
According to this law, an object will not move on its own; it needs something or someone to move it.
Law of Inertia
This is the movement of energy from one object to another.
Energy transfer.
This is the study of the nature of the universe.
Physical cosmology.
What two factors affect the pull of gravity?
Speed and distance.
What is air resistance?
Friction caused by air.
According to this law, the more mass something has, the more force is needed to move it.
Law of Acceleration
How do you calculate momentum?
Multiply the mass and velocity of an object.
According to this, gravity is not a force; it is a curvature in space-time; anything with mass will cause space-time to bend.
The General Theory of Relativity.
What is the difference between a balanced force and an unbalanced force?
A balanced force has two equal opposing forces, leaving an object at rest. An unbalanced force does not have equal opposing forces, causing an object to move.
Morris the cat chased poor 3-year-old Mr. P. through the house and bit him whenever she caught up to him. What kind of energy is this?
Kinetic
This a telescope that uses mirrors to reflect light and form an image.
Reflecting
What is the difference between an elastic collision and an inelastic collision?
In an elastic collision, there is no loss of kinetic energy. In an inelastic collision, there is.
Special Theory of Relativity
