Questions and Answers

What is the difference between speed and velocity?

Speed is a scalar quantity, while velocity is a vector quantity (correct)

Speed is the magnitude of velocity

Speed is measured in meters per second, while velocity is measured in meters per second squared

Speed refers to the rate at which an object changes its position, while velocity refers to the total distance traveled by an object

Which of the following is the correct definition of displacement?

The speed at which an object moves

The total distance traveled by an object

The change in position of an object with respect to time (correct)

The rate at which an object changes its position

Which equation represents instantaneous velocity?

$v = \frac{\Delta t}{\Delta x}$

$v = \frac{d}{dt}(x)$ (correct)

$v = \frac{\Delta x}{\Delta t}$

$v = \frac{\Delta x}{dt}$

Study Notes

Motion in One Dimension

Speed and velocity are often confused, but speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that refers to an object's speed in a specific direction.

Displacement

Displacement is the distance an object travels from its initial to its final position, and it can be positive, negative, or zero.

Instantaneous Velocity

Instantaneous velocity is represented by the equation dv/dt = Δv / Δt, where dv is the change in velocity and dt is the change in time.

Recommended Resources

For learning about motion in one dimension, the recommended reading is "Motion in One Dimension" by OpenStax College Physics.
For learning about motion along a straight line, the recommended video is "Motion Along a Straight Line" by 3Blue1Brown.

Derived Physical Quantities

Velocity is a derived physical quantity, meaning it can be calculated from other physical quantities like displacement and time.

Velocity Calculation

Velocity can be calculated using the equation v = Δx / Δt, where v is velocity, Δx is the change in position, and Δt is the change in time.
