Speed, Velocity, Momentum Definitions ONLY 2024

Front

What is the formula to calculate speed?

Back

Speed = distance / time

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is the formula to calculate acceleration?

Back

Acceleration = Change in velocity / Change in time

Front

What is the unit for momentum?

Back

Momentum is measured in kg·m/s (kilogram meter per second) or Lbs x miles/hour.

Front

What is the unit for velocity?

Back

Velocity can be measured in miles/hour, meters/second, cm/second, or km/hour.

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 momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

How do you calculate momentum?

Back

Momentum = mass x velocity

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude (e.g., speed).

Front

What is a vector quantity?

Back

A vector quantity has both magnitude and direction (e.g., velocity).
