How does physics relate to falling?
The gravitational force is an interaction between two objects with mass. For a falling ball, the two objects with mass are the Earth and the ball. The strength of this gravitational force is proportional to the product of the two masses, but inversely proportional to the square of the distance between the objects.
What is the physics behind free fall?
A free falling object is an object that is falling under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall.
What happens to the velocity of a ball as it is dropped off a cliff?
When the ball comes back down to ground level it has exactly the same speed as when it was thrown up, but its velocity is reversed. This is an example of the law of conservation of energy.
What factors affect the fall of the object?
Drag and gravity are two factors that affect the rate an object falls through air. If the gravity (relative to Earth’s gravity) is greater, the rate would change very quickly from slow to fast, but if the gravity is weaker, it would change slower. Drag slows down an object depending on it’s aerodynamics.
In which condition does a body said to be in freefall?
The only condition for free fall as you said is that the motion of the body should be only under the influence of gravity alone. There should not be any effect of other forces like air resistance, viscous drag etc. The condition depends on the property of the material under free fall.
How do you calculate free fall distance?
Choose how long the object is falling. In this example, we will use the time of 8 seconds. Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s . Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m .
What is the speed at which you fall from a cliff?
But gravity is a powerful force. As you fall, it pulls you toward the earth, or in the case of cliff diving, toward the water, at a speed of 32 feet per second per second (9.8 meters per second per second).
What happens to your body when you jump from a cliff?
When you jump from a cliff, you go into free fall and gravity is the only force acting on your body. You encounter no resistance from friction with the ground as you would when running or skiing, and you suffer negligible air resistance.
How is the force of gravity related to cliff diving?
You encounter no resistance from friction with the ground as you would when running or skiing, and you suffer negligible air resistance. But gravity is a powerful force. As you fall, it pulls you toward the earth, or in the case of cliff diving, toward the water, at a speed of 32 feet per second per second (9.8 meters per second per second).
How to calculate the height of a cliff?
All we need to find the height of the cliff is the time it takes the girl to fall and a simple physics formula. s = x 0 + v 0 t + ½at 2 s (height of cliff) = 0 + 0 + ½ (9.81 m/s 2)* (2.46) 2 height of cliff = 29.7 m or 97.3 ft
