Unit 1: Forces and Interactions

Front

What is a reference point?

Back

A place or object used for comparison to determine if an object is in motion.

Front

What is the unit of measurement for force?

Back

Newton.

Front

What is net force?

Back

The overall force on an object when all the individual forces acting on it are added together.

Front

What is static friction?

Back

Friction that acts on objects that are NOT moving.

Front

Give an example of static friction.

Back

A desk sitting on the carpet.

Front

What is fluid friction?

Back

Friction that occurs when an object moves through a fluid (liquid or gas).

Front

What is the difference between static friction and kinetic friction?

Back

Static friction acts on stationary objects, while kinetic friction acts on moving objects.

Front

What is the effect of mass on gravitational force?

Back

The greater the mass of an object, the greater the gravitational force it exerts.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of objects, affecting their speed and direction.

Front

What is an example of a force?

Back

Gravity, friction, tension, and applied force are all examples of forces.
