Speed, Velocity, Acceleration, Force and Graphing Motion

Front

What is 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).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, combining both speed and direction.

Front

What is acceleration?

Back

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

Front

What is force?

Back

Force is a push or pull acting on an object, measured in newtons (N). It can cause an object to accelerate.

Front

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

Back

A flat line indicates that the object is not moving; it is at rest.

Front

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

Back

A steep slope indicates a high speed; the object is covering a large distance in a short amount of time.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

If a cyclist travels 10 km in 30 minutes, what is their average speed in km/h?

Back

Average speed = 10 km / 0.5 hr = 20 km/h.

Front

What is the unit of force?

Back

The unit of force is the newton (N).

Front

What does acceleration look like on a velocity-time graph?

Back

Acceleration appears as a slope; a positive slope indicates increasing speed, while a negative slope indicates decreasing speed.
