AKS 8a-c Forces & Motion Review

Front

What is velocity?

Back

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

Front

How is speed calculated?

Back

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

Front

What does a constant slope on a distance-time graph indicate?

Back

A constant slope indicates constant speed.

Front

What does an increasing slope on a distance-time graph indicate?

Back

An increasing slope indicates constant acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

If a baseball is thrown 50 meters in 2 seconds, what is its speed?

Back

Speed = Distance / Time = 50 meters / 2 seconds = 25 m/s.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

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

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down, also known as deceleration.

Front

What is the unit of speed?

Back

The unit of speed is meters per second (m/s).
