Because due to the presence of gravity. Gravity is a force that pulls you down. In space there is no gravity so you won't feel this force
It is called Free Fall.
Such an object is said to be in "free fall".
this is a complicated question! initially, air resistance slows objects in free fall down. until a point in which the object reachs terminal velocity! Terminal velocity is when the object is at its maximum speed free falling the air resistance is equal to the acceleration so the object now neither speeds or slows down. also, the bigger the surface area the object has, the higher the air resistance will be, lowering the terminal velocity of the object.
The energy is from the force of gravity pushing the object down the hill, without gravity the object would not fall. The object would remain in place until acted upon by an outside force.
causes the object to fall...
it will slow the fall down a little.
if an object is lightr it will fall slower because gravity wont take it down as fast if it is heavier it will make the gravity pull it down faster
That is called gravity.
The same as on any other object that is in free fall (no matter in what direction it is currently moving): the object will be accelerated downward.
Gravity pulls them down. Newtons Law of Gravity: what goes up must come down. objects fall to the ground because of gravity
An object is in free fall only if its motion is subject to being both only affected by gravity and only moving up or down.
It is called Free Fall.
Such an object is said to be in "free fall".
For example, if you have something in your hand, and open your hand, the object will fall down.
Mass does not cause an object to fall faster.
there is a net force (gravity), which pulls it down, and as stated by newtons law, if the forces are not balanced on an object then the object will accellerate in the direction of the force, in this case, gravity is the force
A falling object.
