5.6D Force and Motion

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What is work in physics?

Back

Work is done when a force moves an object over a distance.

Front

What is a force?

Back

A force is a push or a pull on an object.

Front

What is inertia?

Back

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

Front

What is the effect of mass on the force of gravity?

Back

The force of gravity increases with the mass of the object.

Front

How does changing the surface affect friction?

Back

Changing the surface can increase or decrease friction; for example, sandpaper has more friction than wax paper.

Front

What is the relationship between force and motion?

Back

A force applied to an object can cause it to start moving, stop moving, or change direction.

Front

What is the purpose 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 an elastic force?

Back

An elastic force is the force exerted by a material when it is stretched or compressed.

Front

What is the role of mass in an experiment testing elastic materials?

Back

Mass affects how much an elastic material stretches; heavier masses typically cause more stretch.
