Forces and Motion

Front

What is the definition of speed?

Back

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

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed of an object at a specific moment in time.

Front

How can motion be described when an object is slowing down?

Back

Motion can be described as deceleration or negative acceleration when an object is slowing down.

Front

What does a constant speed indicate about an object's motion?

Back

Constant speed indicates that an object is moving the same distance in equal intervals of time, without speeding up or slowing down.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What does a speed-time graph represent?

Back

A speed-time graph represents how an object's speed changes over time, showing periods of acceleration, constant speed, and deceleration.

Front

What does it mean if a graph shows a horizontal line?

Back

A horizontal line on a speed-time graph indicates that the object is moving at a constant speed.

What is the significance of a downward slope on a speed-time graph?

Back

A downward slope on a speed-time graph indicates that the object is slowing down or decelerating.

How can you identify constant speed on a graph?

Back

Constant speed can be identified on a graph by a straight, diagonal line that slopes upwards.

What is the relationship between distance, speed, and time?

Back

The relationship is described by the equation: Distance = Speed x Time.
