Speed, Velocity, and Acceleration Notes Flashcard

Front

What does a speedometer measure?

Back

Speed

Front

Calculate the average speed if you travel 80 kilometers in 2 hours.

Back

40 km/h

Front

What is the SI unit of acceleration?

Back

Meter per second squared

Front

When are a car’s velocity and acceleration in opposite directions?

Back

When the car is slowing down.

Front

How is velocity different from speed?

Back

Velocity is a vector quantity while speed is a scalar quantity.

Front

Define speed.

Back

Speed is the distance traveled per unit of time.

Front

Define 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 per unit of time.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time

Front

What happens to velocity when an object is in free fall?

Back

Velocity increases due to acceleration from gravity.
