GCSE Physics - The difference between Speed and Velocity & Distance and Displacement #51

The video tutorial explains the concepts of speed and velocity, highlighting the difference between scalar and vector quantities. Speed is a scalar quantity with only magnitude, while velocity is a vector with both magnitude and direction. The tutorial also covers distance and displacement, providing examples to illustrate these concepts. It explains how to calculate speed and velocity using formulas and discusses the use of symbol formulas. The video concludes with real-life examples of speed in various contexts, such as walking, cycling, and sound waves, emphasizing the variability of speed in different situations.

What is the main difference between speed and velocity?

• Speed includes direction, velocity does not.

• Neither speed nor velocity include direction.

• Both speed and velocity include direction.

• Velocity includes direction, speed does not.

Which of the following is a vector quantity?

• Speed

• Displacement

• Distance

How do you calculate the speed of an object?

• Add distance and time

• Subtract time from distance

• Divide distance by time

• Multiply distance by time

What does a negative velocity indicate?

• The object is stationary

• The object is moving forward

• The object is moving backward

• The object is accelerating
