What is Light?
What is reflection
The bouncing of light off an object.
What is inertia?
Inertia is the tendency of objects to resist a change in motion.
What is motion?
Motion is the process of an object changing its place or position.
A person opening the door.
A pull
What is weathering?
The breaking down of rock on Earth´s surface into smaller pieces.
What is refraction?
The bending of light as it passes at an angle from one type of matter into another.
Explain the 3rd Law of Newton
Action and Reaction.
What is force?
A push or a pull.
A person walking his dog.
A pull
What is erosion?
The moving of the pieces or rock.
What is a prism?
A transparent material that separates white light into its components colors by refraction.
Explain the second Law of Newton.
F=m x a
More mass= more force. Less mass= Less force.
What is friction?
Friction is a force that opposes motion.
A lady taking the baby in a stroller.
A push
What is deposition?
The dropping or settling of eroded materials.
What is transparent?
Materials that let light pass through them.
Explain the first Law of Newton.
Inertia: the tendency of objects to stay at rest if they are at rest and to stay moving if they are moving.
What is gravity?
The force of attraction between objects such as the attraction between Earth and the objects in it.
A person closing the door
A push
What is sediment?
sand, bits of rock and other materials carried and deposited by water, wind or ice.
Materials that transmit some light and absorb some light.
What is Opaque?
Materials that do not let light pass through them.
What are balanced forces?
Balanced forces are forces on an object that are equal in size and opposite in direction.
A person climbing the tree with a rope
A pull
What are unbalanced forces?
Forces that cause a change in an object motion because they don´t cancel each other out.
