15 Questions
What is the main difference between speed and velocity?
Speed is always a scalar quantity, while velocity is always a vector quantity.
If a person walks 10 meters to point B and then walks back 10 meters to point A, what is the person's total displacement?
0 meters
What happens to speed if a person walks from point A to B and then back to point A in the same time interval?
Speed doubles
In what units is speed typically expressed?
Meters per second
If an object moves in a circular path at a constant speed, what can you say about its velocity?
The velocity is constant
Which of the following statements is true regarding displacement and distance?
Displacement takes direction into account while distance doesn't.
If an object moves 40 meters in 10 seconds, what is its speed?
$4 m/s$
What information does velocity provide that speed does not?
Displacement in relation to direction
What is the main difference between speed and velocity?
Speed is a scalar quantity, while velocity is a vector quantity.
Which statement accurately describes velocity?
Velocity is the rate of change of position with respect to time.
How does speed differ from velocity in terms of direction?
Speed lacks directional information, while velocity includes direction.
In the context of motion, what does displacement refer to?
Displacement is a change in position from one point to another.
If an object has moved 50 miles south, what quantity would best describe this motion?
Velocity of 50 miles per hour south
Why can the magnitude of speed and velocity differ for the same object?
Because speed uses distance traveled, while velocity uses displacement.
Which quantity plays a role in locating an object in relation to a specific reference point?
Displacement
Learn the difference between speed and velocity and how they describe the motion of an object. Speed is a scalar quantity that indicates how fast an object is moving, while velocity is a vector quantity that includes information about both speed and direction.
