Does it take the same amount of time for an object to go up and down?
Does it take the same amount of time for an object to go up and down?
Both the mass of the object and the mass of the earth are the same respectively at the time when the object goes up and when the object comes back down. The gravitational force between them is equal as well. The time to go up and the time to come down would be equal as well.
What is the time of flight in projectile motion?
The time of flight of a projectile motion is exactly what it sounds like. It is the time from when the object is projected to the time it reaches the surface. The time of flight depends on the initial velocity of the object and the angle of the projection, θ .
How do you find the time it takes to reach maximum height of a projectile?
Determine how high the projectile traveled above its initial height by using the following formula where V is the initial vertical velocity and T is the time it takes to reach its peak: Height = V * T +1/2 * -32.2 ft/s^2 *T^2 For example, if you had an initial vertical velocity of 32.14 ft/s and a time of one second.
Why does it take a ball longer to fall?
When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.
What do you mean by time of flight what will be the expression for it when a projectile is fired horizontally with a velocity u?
Consider a projectile fired with velocity V at an angle θ with horizontal. From equations of motion we write y=ut+21at2. Here, final displacement in y direction =0. ⇒O=Vsinθ.
What is the total time of flight?
This shows that the total time of flight is the sum of the time it takes the object to travel upwards to reach the maximum height and the time it takes the object to travel from the maximum height to the ground level. It should be noted that, the time it takes an object to reach the maximum height from the point of
What is the time of flight of a projectile?
Time of Flight. To find the time of flight, determine the time the projectile takes to reach maximum height. The time of flight is just double the maximum-height time. Start with the equation: v y = v oy + a y t At maximum height, v y = 0. The time to reach maximum height is t 1/2 = – v oy / a y Time of flight is t = 2t 1/2 = – 2v oy…
What is the time of flight at maximum height?
The time of flight is just double the maximum-height time. Start with the equation: v y = v oy + a y t. At maximum height, v y = 0. The time to reach maximum height is t 1/2 = – v oy / a y. Time of flight is t = 2t 1/2 = – 2v oy / a y.
How do you calculate time of flight in physics?
Time of flight is t = 2t 1/2 = – 2v oy / a y Plugging in v oy = v o sin (q) and a y = -g, gives: Time of flight is t = 2 v o sin (q) / g where g = 9.8 m/s 2
