My strategy for solving any projectile motion problem. You need to split the variables in to the x and y directions and solve for time. Sounds simple and it really is, usually.

This is much more personal than my average video. I talk about my spelling inadequacies. (yes, i just spelled inadiquacies incorrectly, spell check fixed it, arg.) I use it as a tool to talk about admitting you don't understand as an...

Catapults were mighty handy for pirates in the golden age of piracy (during the 17th century). And medieval knights used them centuries earlier for taking down massive castle walls. Even Greeks and Romans used catapults about 2,000 years...

Lesson 3 (2D Motion & Kinematics) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this...

You're a mischievous little physicist, aren't you? Well I guess there's no harm in projecting a toy into the air, especially if it's part of your scientific research. Given a spring constant and some other information, how high will this...

How to find the center of mass of an irregularly shaped, flat object.

How to find the center of mass of an object with a missing piece.

Figure skating has become one of the most popular events at the Winter Olympics. Head of the Physics Department at the University of Michigan Brad Orr explains that good balance, or stability, is basic to everything a skater does--and...

Can you drop a ball from a moving vehicle and get it to land in a bucket? You can using Physics! In this video we solve an introductory projectile motion problem involving an initial horizontal velocity and predict how far in front of...

Solving an intermediate projectile motion problem using unit vectors. Also culling information from the quadratic formula.

This is how you include air resistance in projectile motion. It requires the Drag Force and Numerical Modeling (or the Euler Method). It is also very helpful to use a spreadsheet to do the calculations. I prove a statement from a...

AP Physics C: Electricity and Magnetism review of Electric Flux and Gauss’ Law including: Electric flux for a constant electric field, an example of the flux through a closed rectangular box, the electric flux from a point...

Yes, water stays in the bucket. Would you like to know why? Watch the video and learn!

I've seen it a thousand times. Students understand everything during class, but then when it comes time to try the problems on a test, they draw a blank. You just need a solid strategy, and lots of practice! Take a look at this.

Projectile motion is composed of a horizontal and a vertical component. This video shows that via a side-by-side video demonstration and also builds the velocity and acceleration vector diagram.

Projectile Motion summary

Things don't always move in one dimension, they can also move in two dimensions. And three as well, but slow down buster! Let's do two dimensions first. You know, like a cannonball. Isn't this getting fun?

The free body diagram we first learn is not entirely accurate. All of the forces are not drawn from the center of mass of the object. Learn why we start this way and, when we get torque, what the free body diagrams will actually look...

Center of mass is defined and demonstrated in projectile motion. We demonstrate what happens when you push at or near the center of mass. The center of mass of a Feeble is demonstrated. And the “Hang Test” is used to find the center of...

"Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League. In this segment, NBC's Lester Holt looks at the science of projectile motion...
