Exploring Linear Motion Concepts

What is the primary characteristic of linear motion?

• Motion in a straight line

• Motion in a circular path

• Motion in a zigzag pattern

• Motion in a random direction

Which of the following is a vector quantity?

• Time

• Temperature

• Velocity

• Mass

What does a scalar quantity have?

• Both magnitude and direction

• Neither magnitude nor direction

• Only magnitude

• Only direction

How is displacement different from distance?

• Distance is always zero

• Displacement is a scalar quantity

• Distance is a vector quantity

• Displacement is the straight line from start to end point

Which of the following is an example of a scalar quantity?

• 20 meters per second north

• 10 seconds

How is average speed calculated?

• Total displacement divided by total time

• Total time divided by total distance

• Total distance divided by total time

• Total time divided by total displacement

What is the difference between speed and velocity?

• Speed includes direction, velocity does not

• Velocity includes direction, speed does not

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

• There is no difference

If a car travels 100 meters in 10 seconds, what is its speed?

• 10 meters per second

• 100 meters per second

• 1 meter per second

• 0.1 meters per second

What is the displacement of an object that starts and ends at the same point?

• Equal to the distance traveled

• Always positive

• Zero

• Equal to the time taken
