Speed, Velocity, and Acceleration

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units like meters per second (m/s) with a directional component (e.g., 50 m/s east).

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

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

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 does 'm/s²' represent?

Back

'm/s²' represents acceleration, indicating how much the velocity of an object changes per second.

Front

What is motion?

Back

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

Front

What are the units of speed?

Back

Common units of speed include meters per second (m/s) and kilometers per hour (km/h).

Front

What is the formula for calculating acceleration?

Back

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

Front

What is an example of constant speed?

Back

A car traveling at 60 km/h on a straight road without changing speed.
