Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed is a measurement of how fast an object is moving, calculated as distance divided by time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is velocity?

Back

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

Front

How does velocity differ from speed?

Back

Velocity has a direction associated with it, while speed does not.

Front

What is acceleration?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What is a vector quantity?

Back

A vector quantity is a quantity that has both magnitude and direction, such as velocity and acceleration.

Front

What is a scalar quantity?

Back

A scalar quantity is a quantity that has only magnitude and no direction, such as speed and distance.

Front

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

Back

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

Front

What does a constant velocity indicate about an object's motion?

Back

A constant velocity indicates that the object is moving at a steady speed in a straight line without changing direction.
