What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the Earth.

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 balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

How does ramp height affect motion?

Back

Increasing ramp height can increase the distance an object rolls due to greater potential energy.

Front

What is the role of surface texture in motion?

Back

Surface texture affects friction; smoother surfaces allow for easier movement, while rough surfaces increase friction.

Front

What is the purpose of a fair test in an experiment?

Back

A fair test ensures that only one variable is changed at a time to accurately measure its effect.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two variables.

Front

What is the scientific method?

Back

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