Identifying Speed, Velocity, and Acceleration

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, typically measured in meters per second (m/s).

Front

What is Acceleration?

Back

Acceleration is a vector quantity that represents the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down), measured in meters per second squared (m/s²).

Front

How do you calculate Speed?

Back

Speed = Distance / Time. For example, if a car travels 100 km in 2 hours, its speed is 50 km/h.

Front

How do you calculate Velocity?

Back

Velocity = Displacement / Time. Displacement is the straight-line distance from the starting point to the endpoint, including direction.

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 is an example of Constant Speed?

Back

A car traveling at a steady 60 km/h on a straight road is an example of constant speed.

Front

What is an example of Constant Velocity?

Back

A train moving at 80 km/h in a straight line without changing direction is an example of constant velocity.

Front

What is an example of Acceleration?

Back

A car increasing its speed from 20 m/s to 30 m/s in 5 seconds is an example of acceleration.

Front

What happens to Velocity when an object slows down?

Back

When an object slows down, its velocity decreases, indicating negative acceleration.
