Flashcard 25

Front

What is Radiation?

Back

Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Front

What is Motion?

Back

Motion is the change in position of an object with respect to time and its reference point.

Front

What is Time?

Back

Time is a measure of the duration of events and the intervals between them, often considered as a continuous progression.

Front

What is a Variable?

Back

A variable is an element, feature, or factor that is liable to vary or change in an experiment or mathematical equation.

Front

Define Kinetic Energy.

Back

Kinetic energy is the energy that an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential energy is the stored energy of an object based on its position or state, such as gravitational potential energy.

Front

Explain the Law of Conservation of Energy.

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is Speed?

Back

Speed is the distance traveled per unit of time, typically expressed in meters per second (m/s).

Front

Define Acceleration.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is Friction?

Back

Friction is the resistance that one surface or object encounters when moving over another, affecting motion.
