physical science final review

Frame of Reference

A set of coordinates determining the position or velocities of objects.

Distance

Total movement of an object without considering direction.

Vectors

Represent magnitude and direction of an object, often shown with arrows.

Speed

Object's change in distance with respect to time.

Velocity

Object's change in direction with respect to time.

Acceleration

Change in velocity over time.

Forces

Invisible pushes or pulls acting on objects.

Energy

Transferred through forces moving objects.

Waves

Disturbances in matter carrying energy.

Electric Charges

Created by transferring or removing electrons.

Light

Acts as both a wave and a particle.

Universal Forces

Electromagnetic, strong nuclear, weak nuclear, and gravitational forces.

Conservation Laws

Energy cannot be created or destroyed; momentum is conserved.

Renewable Resources

Can be replenished.

Non-renewable Resources

Can run out and not be replaced.

Newton's Laws

Explain motion and forces acting on objects.

Safety Measures in Circuits

Fuses, circuit breakers, and GFCI enhance circuit safety.

Units in Physics

Joules, volts, amps, and watts measure various aspects in physics.
