What happens before terminal velocity takes place?
Before terminal velocity is reached, an object will be accelerating due to the force of gravity. As the object accelerates, air resistance (drag) will increase, which will gradually counteract the force of gravity until the two forces are equal and the object reaches terminal velocity.
Does a skydivers decreases her acceleration when falling 5 seconds before reaching her terminal velocity?
No, a skydiver's acceleration remains constant as they fall towards their terminal velocity. This is because terminal velocity is the point at which the forces of gravity and air resistance are balanced, resulting in a constant velocity.
When does a skydiver have the greatest kinetic energy?
A skydiver have the greatest kinetic energy as he/she wants to hit the water.
Why does an object with a large surface area reach terminal velocity before an object with a small surface area?
An object with a large surface area experiences more air resistance, which increases as the object accelerates. This causes the object to reach terminal velocity quicker compared to an object with a smaller surface area, which experiences less air resistance and takes longer to reach terminal velocity.
How does the weight of a falling body compare with the air resistance it encounters before it reaches terminal velocity?
The weight exceeds the force of air resistance, but as the speed increases the air resistance increases, so the net force (weight - air resistance) falls. When the difference becomes zero the acceleration ceases and you have terminal velocity.
Why is terminal velocity with a parachute open less than the terminal velocity before it was open?
because there is more air resistance
What is absolute velocity is it the other name for the velocity of a free falling body when the net force of air resistance and gravity is zero?
Absolute velocity refers to the speed and direction of an object relative to a fixed point, regardless of any external factors. In the context of a free falling body with zero net force due to air resistance and gravity, its absolute velocity would be constant and equal to the velocity just before air resistance became negligible.

Which has the greatest acceleration a 100-gram a 150 gram or a 200 gram?
None. Assuming they are falling with the same conditions, they accelerate equally. But the 200 gram object has the greatest terminal velocity therefore reaching a higher velocity before resting at a constant speed.
Why does an object with a large surface area reach terminal velocity before an object with a small surface area?
An object with a large surface area experiences more air resistance, which increases as the object accelerates. This causes the object to reach terminal velocity quicker compared to an object with a smaller surface area, which experiences less air resistance and takes longer to reach terminal velocity.

How does initial velocity affect the projectile in range?
The initial velocity of a projectile affects its range by determining how far the projectile will travel horizontally before hitting the ground. A higher initial velocity will result in a longer range because the projectile has more speed to overcome air resistance and travel further. Conversely, a lower initial velocity will result in a shorter range as the projectile doesn't travel as far before hitting the ground.
Does rain reach terminal velocity?
No, raindrops do not reach terminal velocity because they are too small and have a low enough mass that air resistance slows them down before they can reach their maximum falling speed. Terminal velocity is typically reached by larger objects like skydivers or hailstones.
What is terminal velocity for a mouse?
The terminal velocity for a mouse is estimated to be around 10 mph (16 kph). This means that when a mouse falls from a height, it will reach a maximum speed of about 10 mph before air resistance balances the force of gravity.
What is the formula for perfectly elastic collision?
Total momentum before = total momentum afterTotal kinetic energy before = total kinetic energy afterSum of x-components of velocity before = sum of x-components of velocity after.Sum of y-components of velocity before = sum of y-components of velocity after.Sum of z-components of velocity before = sum of z-components of velocity after.
