Scalars, Vectors, Distance, Displacement, Speed and Velocity

A car travels 100 meters south. What is the car's displacement?

• 100 meters

• 100 meters south
• 100 meters north
• 50 meters

An object moves 10 meters north in 2 seconds. What is the object's distance?

• 10 meters north

• 10 meters

• • + 10 meters

• 5 meters north

Why is distance a scalar quantity?

• Distance is a scalar quantity because it has both magnitude and direction.
• Distance is a scalar quantity because it can be positive or negative.

• Distance is a scalar quantity because it only has magnitude and no direction.
• Distance is a scalar because it is measured in meters.

In order to look for speed, what do you need find in the given?

• Distance and time
• Displacement and time

• Distance only

• Displacement only

A man runs at a speed of 1 meter per second. How far did the man travel if he ran for 10 seconds?

• 10 meters
• 1 m/s

• 1 meter

• 10 seconds

What is the formula used to find the distance of an object given speed and time?

• distance = speed x time
• distance = time / speed

• distance = speed / time
• distance = speed + time
