Speed Velocity and Acceleration Practice

Front

What is Speed?

Back

Speed is a scalar quantity that refers to how fast an object is moving. It 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 a vector quantity that refers to the rate at which an object changes its position. It includes both speed and direction, such as 60 km/h east.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can occur when an object speeds up, slows down, or changes direction, measured in meters per second squared (m/s²).

Front

How is Speed calculated?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

How is Velocity different from Speed?

Back

Velocity includes direction, while speed does not. For example, 50 km/h is speed, but 50 km/h north is velocity.

Front

What is an example of constant speed?

Back

An example of constant speed is a car traveling at 60 km/h on a straight road without changing speed.

Front

What is an example of acceleration?

Back

An example of acceleration is a car that speeds up from 20 km/h to 60 km/h in 5 seconds.

Front

What does it mean if an object has a negative acceleration?

Back

Negative acceleration, or deceleration, means the object is slowing down.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed of an object at a specific moment in time.
