In this lesson, we explain the difference between average speed and average velocity in physics. We start by showing that the average velocity is defined to be the displacement of an object divided by the elapsed time during the motion. Because of this definition, velocity is a vector quantity because the displacement is a vector as well.
The speed formula is the exact same equation as the velocity formula with the difference that we take the absolute value of the displacement before doing the calculation. Because of this, speed is defined as distance divided by time elapsed. Speed is not a vector – it is a scalar quantity.
I enjoy your teaching Sir thank you sir
Sir may I have you watch up contact,I'm interest in your explaination ,,,and tutorial lession,here is mind,"Jnr Wakol"

Sir, from the bottom of my heart I want to say keep doing what you are doing. You are so much better than most of my university lecturers. ❤🙌🏽🙏🏾
Continue doing good work sir and remain bless sir
Thank you sir ❤
See speed in air and space vacume. Now i have two vases flasks. See one sea level air one i vacumes aires out. Now i have two barium viles. I pop on in a vacume instant change in aires preasures looks like smokes. But in vacume its attomised and in air its mass. Gap over nose bridge vanishing points horison focus points. See its a triangles. Seas 180°±90° sin tan 270°/3 90is □ said einstines see energy mass creates ² 4² is 8 and thats his mother earth. SWLL. Pigs swill yes. Hogs head. X
Thank u . Excellent
Can it be possible in instances that you are not given the time but distance is given
Am sorry sir,but how do you get 1.67m/s?
THANK YOU… SIR…!!!
In understanding SPACE, what is gravity, TIME, AND time dilation (ON BALANCE), it is important is it to understand what is a BALANCED displacement of what is SPACE. ELECTROMAGNETISM/energy is gravity ON/IN BALANCE.
Consider what is E=MC2. TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Consider TIME AND time dilation ON BALANCE. (c squared CLEARLY represents a dimension of SPACE ON BALANCE.) Indeed, the stars are POINTS in the night sky ON BALANCE. The rotation of WHAT IS THE MOON matches the revolution. Consider what is THE EYE, AND notice what is the TRANSLUCENT AND BLUE sky ON BALANCE. NOW, consider what is the BALANCED MIDDLE DISTANCE in/of SPACE. CLEARLY, BALANCED inertia/INERTIAL RESISTANCE is fundamental (ON BALANCE). “Mass"/ENERGY IS GRAVITY. ON BALANCE, consider what is the orange (AND setting) Sun. “Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE); AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE (ON BALANCE) consistent WITH E=MC2, F=ma, TIME, AND time dilation ON BALANCE. This CLEARLY AND NECESSARILY represents, DESCRIBES, AND INVOLVES what is possible/potential AND actual ON/IN BALANCE, AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Notice what is the fully illuminated (AND setting/WHITE) MOON ON BALANCE. Great. TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Indeed, inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/AS) GRAVITATIONAL force/ENERGY; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). This CLEARLY explains what is E=MC2 AND F=ma ON BALANCE, AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE !! (Consider TIME AND time dilation ON BALANCE.) Great. Indeed, consider WHAT IS THE EARTH/ground ON BALANCE. I have mathematically proven why the rotation of WHAT IS THE MOON matches the revolution, AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Consider TIME AND time dilation ON BALANCE, AS the stars AND PLANETS are POINTS in the night sky ON BALANCE; AS c squared CLEARLY represents a dimension of SPACE ON BALANCE. (Consider what is THE EYE ON BALANCE.) I have mathematically proven what is the fourth dimension, AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) !!! I have explained why what are OBJECTS may fall at the SAME RATE.

thanks
I totally love and understand all your video lessons. It's better than most of the video lessons have been watching ever since I was looking for yours. I would really love it more if you can trying giving us some assignments to do then in your next video lesson you help us do the correction to them. Much love from me.
I have done a lot of math and I want to learn something new. I am switching to physics and your videos is what I need. In fact everything is easy because I know all the math. Thank you
“pos or neg”
Thank you very much. We appreciate that 🙏
Thank you
I've understood this but can someone explain why we can't take the average instead ? If you know, what I mean.
bravo 👏
You are amazing
Learning physics now so I can ace it next year.
Thank you sir
That's good
Hi teacher , your explanation make us understand lesson
A body of mass 250g is released from the top of a building if the body hit the ground a velocity of 4ms calculate the hight of the building. Someone help please.
