Speed Graphs Flashcard

Front

What is speed?

Back

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

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is the formula to find time when speed and distance are known?

Back

Time = Distance ÷ Speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time, without changing its speed.

Front

What is the difference between speed and velocity?

Back

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

Front

If a car travels 120 km in 2 hours, what is its speed?

Back

Speed = 120 km ÷ 2 hours = 60 km/h.

Front

What does it mean if an object has no acceleration?

Back

It means the object is either at rest or moving at a constant speed in a straight line.

Front

How long will it take to travel 300 km at a speed of 100 km/h?

Back

Time = 300 km ÷ 100 km/h = 3 hours.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).
