Force and Motion 5.6D

Front

What is a simple experimental investigation?

Back

A simple experimental investigation tests one variable while keeping other conditions constant.

Front

What is the role of friction in motion?

Back

Friction is the force that opposes the motion of two surfaces in contact. More friction occurs on rough surfaces.

Front

What is the unit of measure for force?

Back

The unit of measure for force is Newton.

Front

What type of force is created when rubbing hands together?

Back

Rubbing hands together creates friction.

Front

What happens to objects dropped from the same height in a vacuum?

Back

In a vacuum, objects dropped from the same height will hit the ground at the same time, regardless of their mass.

Front

What is a variable in an experiment?

Back

A variable is a factor that can change in an experiment. In a simple investigation, only one variable is tested.

Front

What is gravity?

Back

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

Front

How does surface texture affect friction?

Back

Rough surfaces create more friction than smooth surfaces, making it harder for objects to slide over each other.

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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
