A boulder.

∙ 13y agoAs inertia changes in proportion to mass, the feather would definitely have less inertia, having the lower mass of the two. Less inertia = easier to get moving from a position of zero velocity, and easier to stop.

∙ 14y agoAnyone who has ever observed a feather dropping to the ground knows that feathers, in general, float down to the ground slower than the speed at which most rocks fall to the ground. This is because of the friction between the feather and the air is greater than the friction caused by the rock and the air.
If you were asking what will happen if a rock and a feather are dropped from the same height in a frictionless environment (i.e., a vacuum), then they will reach the ground at the same time because the acceleration constant (i.e., gravity) is the same across both objects.

A feather floating in the air has what type of energy?
it has kinetic energy..because its moving.... kinetic energy is if something moves....thats why its kinetic energy
Is a kite flying through the air kinetic energy?
If the feather is moving, it has kinetic energy. If there is room beneath the feather for it to fall, it has potential energy due to gravity.
Is the movement of air from a fan kinetic energy?
If the air is moving, then it has kinetic energy. If the fan is running, then the blade has kinetic energy. Maybe that's where the moving air got its kinetic energy from. If the dog is also walking through the room, then the dog has kinetic energy too, but he probably didn't get his kinetic energy from the fan or the air. On the other hand, a piece of tissue floating through the room could very well have gotten its kinetic energy from the fan, but that kinetic energy had to be carried from the fan to the tissue by the moving air.
Where is kinetic energy?
Kinetic energy is a energy through movement. When some thing moves, it is kinetic energy.
A boulder falling through the air has what type of energy?
a boulder falling through the air still has some potential energy, but some of its potential energy has changed to kinetic energy...so it has both potential and kinetic!

Which has more kinetic energy a lightbulb shining brightly or a feather fluttering in the wind?
Kinetic energy implies there is movement. If there is no movement, there's no kinetic energy.

What type of energy is represesnted by a log floating down a river?
Kinetic energy (the energy of motion). There is also potential energy being converted into kinetic energy.

What is the energy that is transfered through collisions?

Is a marble rolling along at the bottom of a ramp kinetic energy?
Kinetic energy means energy through movement, so yes, it is. Any movement is kinetic energy.
Does a floating feather have both kinetic and potential energy?
If the feather is moving, it has potential energy equal to half of the product of its mass (m) and the square of its velocity (v2), such that EK=(m*v2)/2 If the feather is in the air close to a body of large mass (e.g. Earth), it also has potential energy due to gravity equal to the product of its mass (m), the distance it has available to fall (h), and the local acceleration due to gravity (g), such that EP,G=m*g*h
How is kinetic energy in tennis?
Kinetic energy is energy in motion. So, there is kinetic energy when the ball is moving through the air. There is sciatic energy when the ball is resting on the racket! Hope this helps.
