What is linear motion?

• Motion in a straight line

• Motion in two or three dimensions

• Motion with constant speed and changing direction

• Motion with changing speed and direction

What is constant velocity?

• Moving at a constant speed without changing direction

• Moving at a changing speed without changing direction

• Moving at a constant speed with changing direction

• Moving at a changing speed with changing direction

What is the difference between speed and velocity?

• Speed is a scalar quantity, while velocity is a vector quantity

• Speed is a vector quantity, while velocity is a scalar quantity

• Speed and velocity are the same thing

• Speed and velocity both have magnitude and direction

What is displacement?

• The total distance traveled by an object

• The change in position of an object

• The average speed of an object

• The average velocity of an object

What is the difference between distance and displacement?

• Distance is a vector quantity, while displacement is a scalar quantity

• Distance is a scalar quantity, while displacement is a vector quantity

• Distance and displacement are the same thing

• Distance and displacement both have magnitude and direction

What is average speed?

• The total distance traveled divided by the time interval

• The change in position divided by the time interval

• The total distance traveled multiplied by the time interval

• The change in position multiplied by the time interval

What is average velocity?

• The total distance traveled divided by the time interval

• The change in position divided by the time interval

• The total distance traveled multiplied by the time interval

• The change in position multiplied by the time interval

What is the SI unit of velocity and speed?

• Meters per second (m/s)

• Kilometers per hour (km/h)

• Miles per hour (mi/h)

• Feet per second (ft/s)
