Investigations on Force

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in grams or kilograms.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can occur when an object speeds up, slows down, or changes direction.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls us toward the Earth.

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

How does surface texture affect motion?

Back

Different surface textures create varying amounts of friction, which can affect how far or fast an object moves.

Front

What is the purpose of a controlled experiment?

Back

A controlled experiment tests one variable at a time to see its effect while keeping other variables constant.

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.

Front

What is a hypothesis?

Back

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

Front

What is the role of measurement in experiments?

Back

Measurement provides quantitative data that helps scientists analyze results and draw conclusions.
