Suppose you throw some object near the surface of the earth. If the only significant force on the object is the constant downward gravitational force, we call this "projectile motion." Yes, that ...

I’ve started recreating many of my numerical model tutorials for introductory physics. In the beginning, I had students use spreadsheets to create models. Of course, spreadsheets aren’t very good for ...

Anyone who's ever taken a physics course has learned the same myth for centuries now: that any object thrown, shot, or fired in the gravitational field of Earth will trace out a parabola before ...

This lesson is specifically linked to the OCR Physics A Specification, but should apply to most A Level Physics courses. A bundle is a package of resources grouped together to teach a particular topic ...

As the name suggests, horizontal motion occurs when the object is thrown horizontally, meaning it starts with zero vertical velocity. The only force acting on the object is gravity, causing it to ...

I wish Angry Birds had been around when I was teaching high school physics. Please don’t think of the game as a hate crime against hogs, or an avian anger management program—instead, think of it as a ...

Adding a soft, springy material to a solid projectile leads to a threefold increase in kinetic energy when the projectile is launched upward. Launch sequence. A lineup of plastic projectiles is ...

This is an acceleration physics quiz WITH ANSWERS, which is 3 pages long including the answer key. There are 2 short answer questions (with parts a-d). This motion physics quiz takes students ...

Shock network. A projectile (dark semicircle) generates chains of force in a two-dimensional granular material as the grains absorb the energy of impact. High-speed video (below) shows that energy is ...
