Speed, Velocity, Acceleration

Front

What is Speed?

Back

Speed refers to how fast an object is moving, measured as distance traveled over time.

Front

What is Velocity?

Back

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

Front

What is Acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is the difference between Speed and Velocity?

Back

Speed is a scalar quantity (only magnitude), while Velocity is a vector quantity (magnitude and direction).

Front

What does it mean if an object is in constant motion?

Back

An object in constant motion is moving at a steady speed in a straight line without changing direction.

Front

What are the three types of acceleration?

Back

1. Positive acceleration (speeding up) 2. Negative acceleration (slowing down) 3. Centripetal acceleration (changing direction)

Front

What is an example of Positive Acceleration?

Back

A car speeding up from 20 km/h to 60 km/h.

Front

What is an example of Negative Acceleration?

Back

A car slowing down from 60 km/h to a stop.

Front

What is an example of Centripetal Acceleration?

Back

A car turning around a curve while maintaining speed.

Front

What two factors does Velocity depend on?

Back

Velocity depends on speed and direction.
