Pre AP ICP - Speed and Velocity - Day 5

Front

What is the definition of speed?

Back

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

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units such as meters per second (m/s) with a directional component.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating resultant velocity when two velocities are at right angles?

Back

Resultant Velocity = √(V1² + V2²), where V1 and V2 are the two perpendicular velocities.

Front

If a train is moving at 15 m/s and a passenger throws a ball backward at 15 m/s, what is the ball's velocity relative to the ground?

Back

0 m/s.

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 the resultant velocity of a boat moving at 5 m/s across a river with a current of 3.3 m/s?

Back

6.0 m/s.

Front

What does it mean for an object to have a velocity of 40 m/s north?

Back

It means the object is moving at a speed of 40 m/s in the northern direction.

Front

What is the speed of an object that travels 60 meters in 4 seconds?

Back

15 m/s.

Front

What are the components of velocity?

Back

Velocity has two components: speed and direction.
