What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is a fair test in an experiment?

Back

A fair test is an experiment where only one variable is changed at a time to ensure that the results are valid.

Front

How does mass affect the force needed to move an object?

Back

Generally, the greater the mass of an object, the more force is needed to move it.

Front

What is the purpose of measuring distance in an experiment?

Back

Measuring distance helps determine how far an object has moved, which can indicate the effect of forces acting on it.

Front

What is the role of a spring in a spring launcher?

Back

A spring stores potential energy and converts it to kinetic energy when released, launching an object.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance slows down the motion of falling objects, affecting how quickly they reach the ground.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
