Alief Taylor Acceleration Flashcard

Front

What is average speed?

Back

Average speed is calculated by dividing total distance by total time.

Front

How do you calculate average speed?

Back

Divide total distance by total time.

Front

What is displacement?

Back

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

Front

If a mom pushes a stroller that travels 4.75m, what is the displacement?

Back

4.75m.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit time.

Front

How do you calculate acceleration?

Back

Acceleration = (final velocity - initial velocity) / time.

Front

A bicyclist decreases velocity from 10 m/s to 6 m/s in 2 seconds. What is the acceleration?

Back

-2 m/s².

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

A car starts from rest and reaches 20 m/s in 3.5 seconds. What is the acceleration?

Back

5.7 m/s².

Front

What are the units for acceleration?

Back

The units for acceleration are meters per second squared (m/s²).
