    Why is a projectile a parabola not a semicircle

    Because the force of gravitational acceleration is stronger than the deceleration the projectile experiences. When you view the middle of the flight path, you are dealing with the moments when the vertical velocities are the slowest and horizontal forces appear much more powerful, so that...

    Force Required to Grip an Object

    After using this equation I've come to a few questions and concerns about the physics of it. The only article I could find over the amount of force necessary for a robot hand to hold an object in the air produced the following equation: where is the force required, is the coeffecient of...

    What if the Gravitational Constant were larger?

    In our dimensions, it is ~6.67384 × 10-11 m3 kg-1 s-2. I recall having read a Hawking article a long time ago in which the ideas of greater or smaller variations of this constant were toyed with, and what they would mean for their respective universes (with other constants unchanged from the...
