Plyler Physical Science: Exam Semester 1 Final Study Guide

Flashcards covering key concepts of energy, momentum, and collisions from the semester 1 final study guide.

Potential Energy (Eg)

100% of the energy at the highest point.

Kinetic Energy (Ek)

100% of the energy at the lowest point (before it stops).

Thermal Energy

Energy that flows from a hotter object to a colder object until both reach a common temperature.

Friction

Causes kinetic energy (Ek) to convert to thermal energy (Ethermal) when an object moves.

Gravitational Force (Fg)

The weight of an object, calculated using the formula Fg = mg, where m is mass and g is acceleration due to gravity (9.8 m/s²).

Momentum (p)

The product of mass and velocity, expressed as p = mv.

Elastic Collision

A type of collision where two or more objects collide and bounce off each other.

Inelastic Collision

A type of collision where two or more objects collide and stick together.

Free-body Diagram

A diagram that shows all the forces acting on an object.

Motion Diagram

A diagram that shows the velocity of an object over time, indicating whether it is constant, increasing, or decreasing.
