Which term describes motion without air resistance to gravity?
Projectile motion describes the motion of an object in the absence of air resistance and under the influence of gravity. This type of motion involves the object traveling in a curved path due to the combined effects of its initial velocity and gravitational force.
Why can a freefall occur only when there is no air?
Freefall can occur in the absence of air resistance because the only force acting on the object is gravity. In the absence of air, there is no air resistance to counteract the gravitational force, allowing the object to fall freely.
What part air resistance plays in gravity?
Air resistance is a force that opposes the motion of an object through the air. In the context of gravity, air resistance can affect the speed and trajectory of a falling object. In the absence of air resistance, all objects would fall at the same rate regardless of their mass, as described by the principle of gravitational acceleration.
Without air resistance all objects regardless of their size and mass experience the same acceleration of gravity?
Yes, that is correct. In the absence of air resistance, all objects fall at the same rate due to gravity. This is known as the acceleration of gravity and is approximately 9.8 m/s² near the surface of the Earth.
If you removed air resistance would objects fall with constant acceleration?
Yes. Neglecting the effects of air resistance, all objects near the surface of the earth fall with the same constant acceleration, regardless of their mass/weight.

What are the technologies of law of inerta?
The resistance of an imposing object to change it's movement. Intrinsic to mass,it is present in the absence of gravity.

What type of path does a projectile follow in the absence of air resistance?
Without air resistance, the path of a projectile over a small part of the Earth's surface, under the influence of gravity alone, is always a piece of a parabola ... as long as it's not launched straight up or straight down.
How does ball size affect the time it takes the ball to fall?
The size of a ball does not directly affect the time it takes to fall in the absence of air resistance. In a vacuum, all objects would fall at the same rate regardless of size. This is known as the principle of acceleration due to gravity.
What happens to gravity in vacuum?
In a vacuum, where there is no air or matter, gravity still exists and continues to exert a force on objects. The absence of air resistance may result in faster acceleration of objects in a vacuum compared to in the presence of air.
How do magnets work in space and what effects do they have on objects in a zero-gravity environment?
In space, magnets work the same way as on Earth by creating a magnetic field. In a zero-gravity environment, magnets can attract or repel objects with magnetic properties, but the effects may be different due to the absence of gravity. Objects may move more freely and unpredictably in zero gravity when influenced by magnetic fields.
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute.?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
What happens when there is no air resistance while an object fall?
When there is no air resistance, an object will fall at its terminal velocity, which is the maximum speed it can reach due to gravity alone. In the absence of air resistance, the object will continue to accelerate until it reaches this terminal velocity, experiencing no upward force to oppose its downward motion.
