Week 16 Flashcard - 7th

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass and speed of the object.

Front

How does temperature affect the movement of molecules?

Back

As temperature increases, molecules move faster due to increased energy.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for average speed?

Back

Average Speed = Total Distance / Total Time

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that shows equal distance covered over equal time intervals.

Front

What happens to particles in a cold substance?

Back

In a cold substance, particles have lower kinetic energy and move around less.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of particles also increases.
