Save guides, add subjects and pick up where you left off with your BBC account. This is the maximum velocity it can reach when all the forces are balanced. The size and direction of the resultant ...

Source: NOVA: "Galileo's Battle for the Heavens" This resource was adapted from NOVA: "Galileo's Battle for the Heavens." Galileo thought a great deal about the motion of falling objects. Specifically ...

Falling objects injured three different people in three separate incidents I recently investigated. The common thread: unsecured objects above the victims’ heads. As in any falling-object case, most ...

Our motion perception is remarkably well tuned to detect small changes in speed and direction. For example, soccer goalkeepers need to precisely judge the speed, direction, and curvature of an ...

FALLS are not an exact science. What's safe for a trained stuntman is not the same for a grandparent – but there is a threshold where just about all falls become fatal. If you lean back in your seat ...

I often look at cases where things are falling. We typically call this "free fall" motion because the object is moving only under the influence of the gravitational force. With only the gravitational ...

All objects in the absence of air resistance (friction) fall at the same rate regardless of their mass. Due to gravity the speed of an object dropped from rest from a height will increase at the rate ...

Raindrops have been caught breaking the speed limit. Using drizzle detectors, researchers discovered tiny raindrops falling more than 1.3 times as fast as terminal velocity, the speed at which air ...

If you drop an object, it will fall. It's a motion that we’ve all seen hundreds of times. We’ve also all seen plenty of the moon, which makes one complete orbit around our planet every 27.3 days (as ...
