How is displacement different from distance?

• displacement is a vector, it must have magnitude and direction

• displacement is a vector, it must have magnitude only

• displacement is a scalar, it must have magnitude and direction

• displacement is a scalar, it must have magnitude only

• 15 meters east

• 15 meters west

• 5 meters east

• 5 meters west

The moon orbits the Earth in 28 days. Assuming it has a constant speed, does the moon also have a constant velocity?

• Yes, its speed does not change

• Yes, it has to travel fast to escape gravity

• No, it is speeding up due to gravity

• No, it has a constant speed but it changes direction
