5.6D Force & Motion Review

Front

What is friction?

Back

Friction is the force that opposes the motion of two surfaces in contact. More friction occurs when an object rubs against a rough surface.

Front

What is a force?

Back

A force is a push or pull that can cause an object to change its motion.

Front

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

Back

Conducting multiple trials helps to ensure the results are reliable and accurate by minimizing the effects of random errors.

Front

What should be kept constant in an experiment to ensure a fair test?

Back

Factors such as the method of pulling, the type of surface, and the mass of the objects should be kept constant.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion and causing them to fall.

Front

What is a smooth surface?

Back

A smooth surface has little friction, allowing objects to slide easily over it.

Front

What is a rough surface?

Back

A rough surface has high friction, making it harder for objects to slide over it.

Front

Why is it important to use the same object in an experiment?

Back

Using the same object ensures that differences in results are due to the variable being tested, not differences in the objects.

Front

What is mass?

Back

Mass is the amount of matter in an object, which affects how much force is needed to move it.

Front

What is an experimental design?

Back

An experimental design is a plan for how to conduct an experiment, including the procedures and variables to be tested.
