Physics Flashcard

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves have more energy.

Front

What happens to an object in motion if no external force acts on it?

Back

It continues to move at a constant speed.

Front

How does the height of a ramp affect the speed of a toy car?

Back

Increasing the height of the ramp increases the speed of the toy car.

Front

What type of energy does an object have when it is at rest at a height?

Back

Potential energy.

Front

What is the definition of frequency in physics?

Back

Frequency is the number of wavelengths that pass a fixed point each second.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes direction.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
