Speed, velocity, and acceleration

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.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur when an object speeds up, slows down, or changes direction.

Front

How is speed calculated?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Velocity has a direction associated with it, while speed does not.

Front

What happens to an object's velocity when it accelerates?

Back

The object's velocity changes, which can mean an increase or decrease in speed or a change in direction.

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 acceleration?

Back

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

Front

What is negative acceleration?

Back

Negative acceleration, also known as deceleration, occurs when an object slows down.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.
