Physics Concepts

What is position in physics?

• A measure of how fast an object is moving

• The total path length traveled by an object

• The location of an object relative to a reference point

• The change in position of an object

Which of the following is a scalar quantity?

• Displacement

• Velocity

• Distance

• Force

Displacement is:

• A vector quantity

• A scalar quantity

• Both a vector and scalar quantity

• Neither a vector nor scalar quantity

If an object moves 10 meters north and then 5 meters south, what is its displacement?

• 10 meters

• 5 meters north

• 5 meters south

• 5 meters

What is speed?

• A measure of size

• A scalar quantity

• A vector quantity

• A measure of how fast an object is moving

The SI unit for speed is:

• Meters per second (m/s)

• Meters (m)

• Seconds (s)

• Kilograms (kg)

How is velocity different from speed?

• Velocity includes both magnitude and direction, while speed only has magnitude.

• Speed includes both magnitude and direction, while velocity only has magnitude.

• Velocity is a scalar quantity, and speed is a vector quantity.

• Velocity is a measure of size, while speed is a measure of how fast an object is moving.

What formula is used to calculate speed?

• S = Distance / Time

• V = Displacement / Time

• S = Displacement / Time

• V = Distance / Time

If an object's displacement is 50 meters north in 5 seconds, what is its velocity?

• 10 m/s

• 5 m/s

• 50 m/s

• 250 m/s

Which of the following is NOT a unit for speed or velocity?

• m/s

• km/h

• m^2/s

• cm/s
