5.6D Force and Motion

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact. It slows down or stops moving objects.

Front

What is work in physics?

Back

Work is done when a force moves an object over a distance. It is calculated as Work = Force x Distance.

Front

What is the effect of changing surfaces on friction?

Back

Changing surfaces can increase or decrease friction. For example, sandpaper has high friction, while wax paper has low friction.

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

What is the role of a meterstick in experiments involving force?

Back

A meterstick is used to measure distances, such as the height an object reaches after being launched.

Front

What is the relationship between mass and 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 an experiment?

Back

An experiment is a scientific procedure undertaken to test a hypothesis or demonstrate a known fact.

Front

What is the purpose of conducting multiple trials in an experiment?

Back

Conducting multiple trials helps ensure the results are reliable and reduces the impact of random errors.

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 significance of using the same method in each trial of an experiment?

Back

Using the same method ensures that the results are consistent and that any differences observed are due to the variable being tested.
