STUDY flash cards for Reddick :(

The variable that is chosen to test in an experiment It is manipulated to observe its effect on the dependent variable.

The variable that is measured as a result of an experiment It responds to changes in the independent variable.

Variable that is kept the same to increase the validity of an experiment Ensures that the results are due to the independent variable.

Data that is descriptive and does NOT include numbers Often involves characteristics or qualities.

Data that includes measured values or numbers Used for statistical analysis.

A disturbance or repeated pattern moving through a medium Can transfer energy without transferring matter.

The number of waves that pass a given point in one second Measured in Hertz (Hz).

The length of one unit of a wave Typically measured from crest to crest or trough to trough.

The speed and direction of an object or wave (vector) Indicates how fast and in what direction something is moving.

The location of an object relative to a reference point Essential for understanding motion.

How fast an object is moving (scalar) Does not include direction.

A number value that also has direction Examples include velocity and force.

A number value that only has magnitude Examples include speed and mass.

The rate at which an object changes velocity (vector measured in m/s/s) Can involve speeding up, slowing down, or changing direction.

A push or pull Can cause an object to accelerate.

Diagram of a square that shows all the forces on an object with arrows Helps visualize the net force acting on an object.

The tendency of an object with mass to resist changes in motion Related to Newton’s First Law.

An object’s motion will remain the same unless acted upon by an unbalanced force Also known as the law of inertia.

F = ma Describes the relationship between force, mass, and acceleration.

Every action force has an equal and opposite reaction force Explains interactions between objects.

The unit of force Named after Sir Isaac Newton.

A compression wave, such as sound Particles move parallel to the direction of the wave.

An ‘up and down’ wave, such as a wave in water Particles move perpendicular to the direction of the wave.

The height or amount of energy in a wave Determines the wave’s energy level.
