As the village blacksmith walks along one day he sees a group of monks circling around an apple tree and chanting something about the truth being expanded. When he stops and listens he learns that a …
Circular Motion Centripetal Acceleration Arc Length
One day a little kid is playing with a yo-yo and swinging it around in a circle for his own amusement. Suddenly a crazed physicist walks up and decides to explain the physics of the circular …

Basketball “Hang Time” Physics
The stadium is packed with fans as Michael Jordan flies through the air on his way to the rim. Gravity seems suspended in this “hang time” phenomenon. The hot dog dealer casually explains that by …
One Dimensional Motion Formulas
v = u + at v2 = u2 + 2as s = ut + 1/2 at2 average velocity = (v + u)/2 v: velocity (this is the velocity u combined with increases or decreases due to acceleration) u: velocity (in this case …
Relative Motion & Reference Points
When something is observed it is always observed from some vantage point. If two people are running next to each other it will not seem as if the other is moving, since their relative motion is the …
Car velocity physics – physics velocity
A physics professor drives along in his camry on the highway and covers about 88 feet per second or a velocity of 100 km/h when he observes a mitsubishi GT 3000 that races out onto the freeway. This …
