Review: Mod. 1The Kinematic Equations

Front

What is velocity?

Back

Speed in a specific direction.

Front

What is acceleration?

Back

A change in velocity over time.

Front

If a dog accelerates at +1.6 m/s² for 3 seconds, how far does he run?

Back

7.2 meters.

Front

What does a decreasing velocity indicate?

Back

The object is slowing down.

Front

What does a graph showing no change in position represent?

Back

Not moving.

Front

What is the formula for calculating distance when acceleration is constant?

Back

Distance = initial velocity × time + 0.5 × acceleration × time².

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the unit of acceleration?

Back

Meters per second squared (m/s²).

Front

What does constant speed mean?

Back

An object covers equal distances in equal intervals of time.

Front

What is displacement?

Back

The shortest distance from the initial to the final position of an object.
