Force, Motion and Graphing Motion

Front

What is the definition of speed in physics?

Back

Speed is the distance traveled per unit of time, typically expressed in meters per second (m/s) or kilometers per hour (km/h).

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that slopes upwards (for positive speed) or downwards (for negative speed) at a consistent angle, indicating that the object is moving at a steady rate.

Front

How do you calculate speed?

Back

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

Front

What does it mean when a graph shows an object has stopped?

Back

A graph shows an object has stopped when the line is horizontal, indicating that there is no change in position over time.

Front

What is the significance of the slope in a distance-time graph?

Back

The slope of a distance-time graph represents the speed of the object; a steeper slope indicates a higher speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, indicating how quickly an object is speeding up or slowing down.

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 decreasing slope on a distance-time graph indicate?

Back

A decreasing slope on a distance-time graph indicates that the object is slowing down.

Front

What is the formula for calculating acceleration?

Back

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

Front

What does a horizontal line on a velocity-time graph represent?

Back

A horizontal line on a velocity-time graph represents constant velocity, meaning the object is moving at a steady speed without acceleration.
