Is it possible for an object in freefall to have no acceleration?
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
What is the difference between freefall and a non freefall?
Freefall is when an object falls under the influence of gravity alone, without any other forces acting on it. In a non-freefall scenario, objects may experience other forces such as air resistance or propulsion that affect their motion.
Are objects in freefall weightless?
Objects in freefall are not weightless; they still have mass and therefore experience the force of gravity. However, in freefall, they are accelerating towards the Earth due to gravity, which gives the sensation of weightlessness as the force of gravity is canceled out by the acceleration.
What is the formula t calculate acceleration?
The formula to calculate acceleration is: acceleration = (final velocity - initial velocity) / time.
How do you calculate speed when you have the force mass and acceleration?
You can calculate speed by dividing the force by the mass to get acceleration, and then multiplying the acceleration by time. Speed = acceleration x time.
What does freefall acceleration depend on?
Acceleration is change in velocity. So it depends on both velocity and time.

In freefall heavier objects fall with a greater acceleration than lighter objects A True b false?

What is the formula t calculate acceleration?
The formula to calculate acceleration is: acceleration = (final velocity - initial velocity) / time.
How do you calculate speed when you have the force mass and acceleration?
You can calculate speed by dividing the force by the mass to get acceleration, and then multiplying the acceleration by time. Speed = acceleration x time.
What is the value of acceleration of an object in freefall?
If the object is falling close to earth the acceleration would be 9.81m/s^2. Be sure to define direction as positive or negative in the problem! (When I do problems I like to define the down direction as positive so I don't have to deal with too many negatives)
What is the formula to calculate the net acceleration of an object?
The formula to calculate the net acceleration of an object is: Net Acceleration (Final Velocity - Initial Velocity) / Time.
Is it true that to calculate acceleraltion you need to know both the final and the initial velocity of an object?
No. That's only one of several possibilities. -- with initial velocity, distance, and time, you can calculate acceleration -- with final velocity, distance, and time, you can calculate acceleration -- with force and mass, you can calculate acceleration -- with initial and final momentum, you can calculate acceleration -- with initial and final kinetic energy, you can calculate acceleration -- with mass, velocity at either end, and kinetic energy at the other end, you can calculate acceleration And I'm sure there are several more that I've missed.
How to calculate velocity using acceleration and time?
To calculate velocity using acceleration and time, you can use the formula: velocity acceleration x time. Simply multiply the acceleration by the time to find the velocity.
Acceleration of freefall due to gravity?
At or near the surface of the earth, it's 9.8 meters (32.2 feet) per second2 . It's different at significant altitudes above the earth's surface, or on the surface of other, extraterrestrial bodies.
