Speed and Graphs

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in miles per hour (mph) or kilometers per hour (km/h).

Front

How do you calculate distance?

Back

Distance can be calculated using the formula: Distance = Speed × Time.

Front

What is constant speed?

Back

Constant speed means an object is moving at the same speed throughout its motion, without speeding up or slowing down.

Front

What does a speed-time graph show?

Back

A speed-time graph shows how speed changes over time, indicating whether an object is accelerating, decelerating, or moving at a constant speed.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its speed, measured in units like meters per second squared (m/s²).

Front

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

Back

A horizontal line indicates that the object is moving at a constant speed.

Front

What does a sloping line on a speed-time graph represent?

Back

A sloping line indicates that the object is either accelerating (if the slope is upward) or decelerating (if the slope is downward).

Front

What is the formula for calculating speed?

Back

Speed = Distance ÷ Time.

Front

If a car travels 300 miles in 3 hours, what is its speed?

Back

Speed = 300 miles ÷ 3 hours = 100 miles per hour.

Front

What does it mean if an object is stationary?

Back

An object is stationary if it is not moving and its speed is 0.
