Where would you weight more, on Earth or on the Moon?

Back

You would weigh more on Earth due to its greater gravitational pull compared to the Moon.

What is the INDEPENDENT VARIABLE in an experiment testing how the amount of water affects plant growth?

Back

The amount you water each plant is the independent variable.

Front

What kind of energy is present in a rock at the edge of a cliff?

Back

The rock has potential energy due to its position.

Front

How far does a freely falling object fall in 6 seconds?

Back

A freely falling object will have fallen about 180 meters after 6 seconds.

Front

True or false: when the distance an object moves is zero, the work done on the object is also zero.

Back

True. If there is no movement, no work is done.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

Define kinetic energy.

Back

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

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the difference between independent and dependent variables?

Back

The independent variable is manipulated in an experiment, while the dependent variable is measured.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².
