What is friction?

Back

A force that opposes the motion of an object, often caused by surfaces rubbing against each other.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal, causing a change in motion.

Front

What is gravity?

Back

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

Back

The upward force that allows an airplane to rise off the ground.

Front

What is drag?

Back

A force that opposes an object's motion through a fluid, such as air or water.

Front

How does surface texture affect friction?

Back

Smoother surfaces have less friction, while rougher surfaces have more friction.
