Forces & Patterns of Motion

Front

What happens to objects that have balanced forces acting on them?

Back

They do not change their motion; they remain at rest or move at a constant speed.

Front

What is the pattern of motion of a pendulum?

Back

The pendulum swings back and forth in a regular pattern.

Front

Does changing the length of the string of a pendulum affect its pattern of motion?

Back

No, it does not change the pattern of motion, but it does affect the time it takes to swing.

Front

How can a sprinter's motion around a track be described?

Back

The sprinter's motion can be described as moving in cycles.

Front

What is a force?

Back

A force is any push or pull on an object.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, change direction, or change shape.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is inertia?

Back

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

Front

What is a pattern of motion?

Back

A pattern of motion is a repeated movement that can be described in terms of direction and speed.
