7.7 Motion and Forces Unit 2

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, measured in units like meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to change its state of motion.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What does a straight line with a positive slope on a distance-time graph represent?

Back

It represents an object moving at a constant speed.

Front

What does a straight horizontal line on a distance-time graph indicate?

Back

It indicates that the object is at rest.

Front

How does velocity differ from speed?

Back

Velocity includes both magnitude and direction, while speed only includes magnitude.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction.
