Distance divided by speed equals time. If I want to travel 20 meters with a speed of 10 meters per second it will take me 2 seconds, (20 m / 10 m/s = 2 s). Let tsp equal the students time to the puddle, tbp equal the buses time to the puddle, and v2 equal the speed of t...
Thus speed is a scalar. Just as we need to distinguish between instantaneous velocity and average velocity, we also need to distinguish between instantaneous speed and average speed.Instantaneous speed is the magnitude of instantaneous velocity. For example, suppose the airplane passenger at one ...
Explain the difference between average velocity and instantaneous velocity. Describe the difference between velocity and speed. Calculate the instantaneous velocity given the mathematical equation for the velocity. Calculate the speed given the instantaneous velocity.We...
This lesson explains the concept of speed in physics. It contrasts it with velocity, presents its formula, and shows how to calculate it to solve...
This topic covers “Speed, Velocity and Acceleration” of O Level Physics (Equivalent to American high school diploma). We will dive into key aspects: Distance vs. Displacement, differentiating Speed from Velocity, understanding Acceleration, mastering Equations of Motion, and interpreting Kinematics Gra...

Quantities that have a magnitude and direction are called vectors. Velocity is a vector, because velocity is speed in a given direction. Example : A boy walks in a positive direction and then back again with a constant speed of 2 m/s, so he walks with a velocity of +2 m/s and then...
