Vectors and Speed Concepts

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as velocity or displacement.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction, such as speed or distance.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

If a batter hits a double, how far does he run if the distance between bases is 90 ft?

Back

180 ft.

Front

What is the total distance traveled if Joe rides his bike from point A to point B (5 m) and then to point C (2 m)?

Back

7 m.

Front

What is the average speed of a car that moves 1000 m in 36 seconds?

Back

28 m/s.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the starting point to the endpoint.

Front

What does it mean if a speed is described as 17 m/s, East?

Back

It means the speed is a vector quantity, indicating both the speed (17 m/s) and the direction (East).

Front

If a car travels 360 m in 12 seconds, what is its speed?

Back

30 m/s.

Front

What is the formula for calculating time when distance and speed are known?

Back

Time = Distance / Speed.
