I have to make up or find a problem that invovles free fall velocity AND relative velocity! Can anyone find/make up a problem for that? HELP!
Free fall is the motion of an object under the sole influence of gravity, where the only force acting on the object is the force of gravity. Relative velocity is the velocity of an object in relation to a reference point or observer.
Some common examples of free fall include objects falling from a height, skydiving, and roller coasters. Relative velocity can be seen in situations such as a person walking on a moving train or a boat traveling downstream in a river.
In free fall, an object's velocity is constantly changing due to the acceleration of gravity. Relative velocity takes into account the movement of both the object and the observer, so in free fall, the relative velocity would be the sum of the object's velocity and the observer's velocity.
The equation for calculating free fall is v = gt, where v is the final velocity, g is the acceleration due to gravity, and t is the time. The equation for relative velocity is v = u + v0, where v is the relative velocity, u is the velocity of the object, and v0 is the velocity of the observer.
Air resistance, or drag, can affect an object's free fall by slowing down its descent. This means that the acceleration due to gravity is not constant, and the object's velocity will not change at a constant rate. Air resistance also affects relative velocity by changing the velocity of the object in relation to the observer, as the object's movement is influenced by the resistance of the air.
