Front

What is kinetic energy?

Back

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

Front

What is a half-pipe in skateboarding?

Back

A half-pipe is a U-shaped ramp used in skateboarding and other extreme sports, allowing riders to perform tricks by gaining speed and height.

Front

What is the relationship between frequency and wavelength in waves?

Back

Wavelength decreases as frequency increases. This means that higher frequency waves have shorter wavelengths.

Front

What is a scientific model?

Back

A scientific model is a representation of an object, system, or concept that helps to explain and predict phenomena.

Front

What is a scientific law?

Back

A scientific law is a statement that describes a natural phenomenon that always occurs under specific conditions.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be an increase or decrease in speed.

Front

What does a graph showing constant speed look like?

Back

A graph showing constant speed is a straight line with a constant slope, indicating that distance increases at a steady rate over time.

Front

What is deceleration?

Back

Deceleration is the process of slowing down or reducing speed.

Front

What is the purpose of using models in scientific investigations?

Back

Models are used because they can simplify complex systems, be safer to work with, and may represent things that are too large, small, or dangerous to study directly.

Front

What is the difference between a theory and a law in science?

Back

A theory is an explanation of a phenomenon based on observations and experiments, while a law describes a consistent relationship observed in nature.
