Motion - Speed, Velocity and Acceleration Study Guide

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/h) or meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

What is velocity?

Back

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

Front

How does velocity differ from speed?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is negative acceleration (deceleration)?

Back

Negative acceleration occurs when an object slows down, resulting in a decrease in velocity.

Front

What units are used to measure acceleration?

Back

The standard unit for acceleration is meters per second squared (m/s²).

Front

If a car travels 100 meters in 5 seconds, what is its average speed?

Back

Average Speed = 100 meters / 5 seconds = 20 m/s.
