Speed, Velocity and Momentum Review

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is velocity?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

How is speed calculated?

Back

Speed is calculated using the formula: Speed = Distance / Time.

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 does a constant speed graph look like?

Back

A constant speed graph is a straight line on a distance-time graph.

Front

What does acceleration mean?

Back

Acceleration is the rate of change of velocity over time.

Front

How do you calculate momentum?

Back

Momentum is calculated using the formula: Momentum (p) = Mass (m) x Velocity (v).

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg·m/s).

Front

What happens to momentum in a collision?

Back

In a closed system, the total momentum before the collision equals the total momentum after the collision (conservation of momentum).
