speed and motion 2023/24

Front

What is speed?

Back

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

Front

How do you calculate distance?

Back

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

Front

What is a reference point?

Back

A reference point is a place or object used for comparison to determine if another object is in motion.

Front

What is the formula for speed?

Back

Speed = Distance ÷ Time.

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that shows equal distance covered in equal time intervals.

Front

What does an increasing speed graph indicate?

Back

An increasing speed graph shows that the object is accelerating, covering more distance in the same time intervals.

Front

If a motorcycle travels at 20 m/s for 500 seconds, how far does it travel?

Back

Distance = Speed × Time = 20 m/s × 500 s = 10,000 m.

Front

If a man runs at 70 m/s for 30 seconds, what distance does he cover?

Back

Distance = Speed × Time = 70 m/s × 30 s = 2100 m.

Front

What does a graph showing a downward slope represent?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
