Calculating the force in a wide range of situations is crucial to physics. Most of the time, Newton's second law (F = ma) is all you need, but this basic approach isn't always the most direct way to tackle every problem. When you're calculating force for a falling object, there are...

Air Resistance:Defined as an opposing force against an object's direction of motion and is defined by the formula {eq}-bv {/eq} Where b equals the drag coefficient of 0.05 for air and v equals the object's velocity. It should be ...
If air resistance/drag were to impact the motion of the falling object when would that be most obvious soon after release, or just before the object hits the ground? Recall that turbulent drag can be estimated using the formula...
Free Fall An object moving only under the influence of the gravitational force is in free fall. The acceleration of an object in free fall on Earth is 9.8 m/s2. For free fall, neglect air resistance! Free Fall Free body diagram Only under the influence of gravitational force. No air resi...
So just what is this literally earth-shattering formula? E stands for rest energy, m for mass, and c for the speed of light, which is 186,000 mi (297,600 km) per second. Squared, this yields an almost unbelievably staggering number. Hence, even an object of insignificant mass posses...
Let us first con- sider a solid spherical object falling through the fluid. Its equation of motion in Stokes flow (small Ga), rendered dimensionless with the same scales as before, is ! GaH€ ~ 1{ 1 r Ga{ 9 2r H_ ð1zOðGaÞÞ, ð8Þ where H is the vertical location...
Solve the formula for tA rock is thrown from the top of a building with a speed of 40.0 m/s and an angle of 55.0 deg above the horizontal. It strikes the ground after 3.50 seconds. Find the height of the building.The velocity of an obj...
