Below is the rule for calculating the velocity of a falling object?
If you can ignore the effects of air resistance, then . . .The speed of a falling object isS = s0 + G TS = speed at any time after it's droppeds0 =initial speed you gave it when you dropped it; if you just openedyour hand and let it roll out, then s0 is zero.G =acceleration of gravity; On Earth: 9.8 meters (32.2 feet) per second2T =length of time it has been falling.That's the speed of the falling object, also the magnitude of its velocity.The direction of velocity is on a line toward the center of the Earth, typicallyreferred to in most places as "down".
How will the upward force of air resistance compare to the downwward pull of gravity?
Assuming that you're referring to an object that is accelerating towards a massive body by means of gravitational attraction... When the force of frictional air resistance equals the opposing force of gravity, the net force on the object equals zero, and acceleration will cease. It is called terminal velocity, and the object will remain at this velocity until some new event happens.
What is the upward acceleration of a falling object?
If you are ignoring wind and other variables then the upward acceleration is negative velocity caused by gravity. So in most cases (-9.8 m)/(s^2)
Are the direction of the velocity and acceleration of a falling body the same?
For the most part, yes; once at terminal velocity, there is no acceleration, so it has direction.
Is it ok if falling objects are not exactly 9.8?
Objects in freefall only accelerate at 9.8m/s2 if air resistance is ignored. Because friction will gradually cause a falling object to reach terminal velocity, most objects won't accelerate at exactly 9.8m/s2.
Can an object have an eastward velocity while experiencing a westward accelerations?
The answer is yes and no.Acceleration is the rate of change of velocity. Velocity is speed plus direction.If an object is travelling eastward and slowing down in a straight line then its velocity is decreasing, it is still travelling eastward. However the force slowing the object is a westward force.A reducing acceleration (slowing down) is most often called a deceleration or negative acceleration. So you have a negative eastward acceleration.
When an object is falling its motion is most affected by air resistancce when?
The faster it falls, the more it is affected by air resistance, since air resistance increases with speed. What usually happens in practice is that the object falls faster and faster, and eventually approaches the "terminal velocity" - a speed at which the force of gravity and the force of friction are in balance.
Does increasing the mass or velocity have the most affect on an object's kinetic energy?
Increasing an object's velocity has a greater effect on its kinetic energy than increasing its mass. This is because kinetic energy is directly proportional to the square of the object's velocity, while it is linearly proportional to the object's mass.
How do you know if an object has the most kinetic energy?
The object with the most kinetic energy is typically the one with the highest velocity, as kinetic energy is directly proportional to the square of velocity. Therefore, an object moving at a faster speed will have more kinetic energy compared to an object with a slower speed, assuming they have the same mass.
What has the most kinetic energy?
An object with a greater mass and velocity will have the most kinetic energy. The kinetic energy of an object is calculated using the formula KE = 0.5 x mass x velocity^2.
If velocity is positive which would most likely yield a negative acceleration?
If an object is moving in the positive direction, a negative acceleration would most likely occur if the object is slowing down, such as when it is decelerating or coming to a stop. Negative acceleration indicates that the object's velocity is decreasing over time.
What is the mass of an object multiplied by its velocity?
The product of an object's mass and velocity is known as momentum. Momentum is defined as mass times velocity and is a vector quantity, meaning it has both magnitude and direction. It is often denoted by the symbol "p."
