Forces & Patterns of Motion

Front

What unit is used to measure force?

Back

Newtons

Front

What happens to the motion of an object when a force is applied?

Back

The object will accelerate in the direction of the force.

Front

What is defined as any push or pull on an object?

Back

A force.

Front

What is the term for forces that are equal in size but opposite in direction?

Back

Balanced forces.

Front

What is the term for forces that are unequal and cause a change in movement or direction?

Back

Unbalanced forces.

Front

Describe the motion of a pendulum.

Back

A pendulum swings back and forth in a regular pattern.

Front

What is the effect of unbalanced forces on an object?

Back

They cause the object to accelerate or change direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect the motion of an object when a force is applied?

Back

Greater mass requires a larger force to achieve the same acceleration.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, F = ma (Force equals mass times acceleration).
