Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, measured in units like meters per second (m/s) or miles per hour (mph).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, such as 55 miles per hour south.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can involve speeding up, slowing down, or changing direction.

Front

How is speed different from 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 has zero acceleration?

Back

An object has zero acceleration if it is not changing its speed or direction, meaning it is either at rest or moving at a constant speed.

Front

Give an example of positive acceleration.

Back

A car speeding up from 20 mph to 60 mph is an example of positive acceleration.

Front

Give an example of negative acceleration (deceleration).

Back

A car slowing down from 60 mph to a stop is an example of negative acceleration.

Front

What is uniform motion?

Back

Uniform motion occurs when an object moves at a constant speed in a straight line.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating acceleration?

Back

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