1D Motion Quiz 1

Imagine you're a pilot flying an airplane. You're currently heading East. In this scenario, would the Eastward movement of your airplane be considered to have a negative or positive velocity? Consider the standard conventions of a coordinate system.

• Negative

• Positive

Imagine you're a pilot flying a plane. You're currently heading North. Suddenly, you receive a command to change your direction and move South. In this scenario, would the Southward movement of your plane be considered as having a negative or positive velocity? Consider the standard conventions of a coordinate system.

• Negative

• Positive

Imagine you're a scientist conducting an experiment. You have an object at rest on a frictionless surface. When you start your experiment, what would be the original velocity of this object?

• It depends on the specific conditions of the experiment

• 0

• It is always positive, regardless of the conditions

• It is always negative, regardless of the conditions

Imagine you're a scientist conducting an experiment. You've just dropped a ball from a certain height and it eventually comes to a stop after bouncing a few times. In this scenario, what would be the ball's final velocity?

• It depends on the specifics of the experiment

• 0

• It's always positive, regardless of the circumstances

• It's always negative, regardless of the circumstances

Imagine you're a scientist conducting an experiment. You have an object that you've carefully placed at rest on a frictionless surface. If you let the object move freely without any external force, what would be its final velocity?

• It depends on the specific parameters of the experiment

• It remains at rest (0 velocity)

• It accelerates downwards at -9.8m/s²

• It always moves with a positive velocity

Imagine you're a physics student studying motion. You come across various types of graphs representing different types of motion. Can you identify which graph among the following represents zero acceleration, also known as constant velocity? Remember, a constant velocity means the object is moving at a steady speed in a straight line.

• Graph A

• Graph B

• Graph C

• Graph D

Imagine you're a scientist studying motion and you come across various measurements. Which of the following measurements would you classify as a velocity?

• A car moving 35 meters towards East

• A bird flying at a speed of 22 m/s

• A train moving at 40 mph towards West

• An object accelerating at 12 m/s²

Imagine you're a scientist studying the motion of objects. You come across a term 'Velocity'. Can you tell what it is? Velocity is...

• The rate of change of acceleration

• The rate of change of displacement

• The rate of change of distance

• The rate of change of speed

Imagine you're a physicist studying motion. You come across two types of quantities - vector and scalar. Can you distinguish between them? Specifically, what is the difference between a vector quantity and a scalar quantity?

• A scalar has a magnitude and direction and a vector has only a magnitude

• A vector has a magnitude and direction and a scalar has only a magnitude

• A scalar has a direction and a vector has a magnitude

• None of the above

Imagine you are a birdwatcher observing a rare species of bird in its natural habitat. The bird you are observing flies at a speed of 2.8 m/s. If the bird continues to fly at this speed for a full 4.33 minutes, how far would the bird have traveled in that time?

• 0.64 m

• 12.12 m

• 92.8 m

• 727.4 m
