How far will a freely falling object have fallen from a position of rest when its instantaneous speed is 27 m per s?
Acceleration of gravity = 9.8 m/s2To reach speed of 27 m/s takes (27 / 9.8) secondsAverage speed during that interval = 1/2 (initial speed + final speed) = 27/2 m/s.Distance = (average speed) x (time) = (27/2) x (27/9.8) = 37.19 meters.
The sumof the kinetic and potential energies of a freely falling body is?
If the body is freely falling, this sum will remain constant.
Does an object that is freely falling have mass?
Yes, mass is an intrinsic property of matter. However a freely falling object will experience no weight.
What changes in a freely falling body?
Velocity
How equation of motion are modified for freely falling objects?
The equation of motion is not modified. Net force = mass x acceleration, whether freely falling or not.
How far will a freely falling object have fallen from a position of rest when its instantaneous speed is 6 ms?
1.8 m

How far will a freely falling object have fallen from a position of rest when its instantaneous speed is 13 meters per second?
Since it is a free-fall motion, this means that acceleration is constant (=g) and therefore, Newton's equations of motion can be used. v2 = u2 + 2as where v is the final velocity u is the initial velocity a is the acceleration and s is the displacement of the body In this case, v = 13 ms-1 , u = 0, a = g ms-2 s = 132/2g m Taking g to be 10, s = 8.45 m (ans)
What is freely body?
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
Where does the law of gravity operate?
Freely falling bodies
What is a freely falling projectile?
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
What are the factors affecting freely falling bodies?
force and gravity
When a body is falling freely which force act on it?
no force act on it
