Motion and Graphing Motions

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 formula for calculating speed?

Back

Speed = Distance / Time.

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

What does a horizontal line on a distance-time graph indicate?

Back

A horizontal line indicates that the object is not moving; it is stationary.

Front

What does a steep slope on a distance-time graph represent?

Back

A steep slope indicates a high speed; the steeper the slope, the faster the object is moving.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

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

Front

What is the SI unit for speed?

Back

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

Front

What does a velocity-time graph show?

Back

A velocity-time graph shows how an object's velocity changes over time.
