A falling object accelerates at a rate of 9.8 m/s2. That means that for every second that it is falling, its velocity increases by 9.8 m/s. The higher that the object is falling from, the longer it will have to speed up, thus the higher its velocity upon impact will be. (This is assuming that it does not reach terminal velocity, the velocity at which an object can no longer accelerate because it is travelling so fast that the drag force (air resistance) is equal to the force of gravity.)

### What kind of energy is in a falling object?

Kinetic energy of a falling object can be calculated for a specific height at a specific point since a falling body accelerates which means that it's velocity is changing every moment. To calculate the kinetic energy of a falling body at a certain height, we should know the mass of the body and its velocity at that point.Then we can apply the following formula: K.E. of an object = 1/2(mv2)

Velocity

### What is the relationship of height of a free falling object in terms of final velocity and its time of fall?

The height where from the body is dropped ie h is given as h = v2 / 2g and h = (1/2) g t2 v is the final velocity and t is time of falling g = acceleration due to gravity

### What causes a falling object to reach terminal velocity?

Its the air resistance that causes the free falling body to reach its terminal velocity

### A body falling freely from a height towared the earth moves with uniform?

... accelerates at approx 9.81 metres per second squared and experiences weightlessness. Friction with the air prevents continuous acceleration and the falling body reaches a maximum velocity called the terminal velocity.

### What happpens to velocity as a drop distance increases relate this to the concept of terminal velocity?

A falling body initially falls at a rate of -9.8m/s2, the acceleration due to gravity. Because of the drag force of the air, which is an upward force that opposes the force of gravity, the body's acceleration will decrease as it continues falling. When the drag force equals the weight of the falling body, there will be no further acceleration, and the body will have reached terminal velocity.

### Are the directions of the velocity and acceleration of a falling body the same?

Yes, both are directed downward.

### Can a object falling from a height be in equilibrium in mid air?

Yes. An object is in equilibrium if the velocity is constant. A constant velocity can occur if the forces balance on the object. Consider that the gravitational force is balanced by the "air resistance force", then there is no net force and thus no acceleration. Then the velocity at which this occurs will be a constant and thus the body will be in equilibrium.

### Are the direction of the velocity and acceleration of a falling body the same?

For the most part, yes; once at terminal velocity, there is no acceleration, so it has direction.

### Are the directions of the velocity and acceleration of a falling body they same?

Yes, as long as gravity is the only force acting on the body.

### 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?

yes. also called terminal velocity.

### What Factors affect the amount of inertia of body?
