Speed Velocity and Acceleration Practice

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, defined as distance divided by time with a directional component.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly an object is speeding up or slowing down.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

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

If a car travels 100 km in 2 hours, what is its speed?

Back

Speed = 100 km / 2 hours = 50 km/h.

Front

What does it mean if an object has a constant velocity?

Back

It means the object is moving at a constant speed in a straight line without changing direction.

Front

What is an example of acceleration?

Back

A car speeding up from 20 m/s to 60 m/s is an example of acceleration.

Front

What is negative acceleration?

Back

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

Front

How can you determine if an object is accelerating?

Back

An object is accelerating if its speed or direction changes over time.
