Will a heavier object hit the ground first?
In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object.
Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one..
Will 2 objects fall same speed?
They think that gravity acts more on a heavier object thus pulling it down faster. In fact, gravity works independently of mass. This means that all objects should fall at the same rate. … If there is no air resistance, or the same amount of air resistance, then objects of the same mass will fall at the same rate.
Does a feather fall as fast as a brick?
You may wonder, then, why feathers float gently in the breeze instead of falling to the ground quickly, like a brick does. Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. … Air resistance causes the feather to fall more slowly.
What is the potential energy formula?
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
What are 4 examples of potential energy?
Examples of Gravitational Potential EnergyA raised weight.Water that is behind a dam.A car that is parked at the top of a hill.A yoyo before it is released.River water at the top of a waterfall.A book on a table before it falls.A child at the top of a slide.Ripe fruit before it falls.
Why is potential energy highest at the top?
Because mass and gravity are constant for the train, if the height of the train above the ground is increased, the potential energy must also increase. This means that the potential energy for the roller coaster system is greatest at the highest point on the track: the top of the lift hill.
Will a rock or feather hit the ground first?
If you drop a feather and a rock at the same time, you know the rock will hit the ground first and the feather will fall much slower.
Which object has the most potential energy?
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds.
Which object has the least potential energy?
When an object has the LEAST potential energy is when it has the MOST kinetic energy.
Which ball has the greatest potential energy?
Ball DWhy? Ball D has the greatest potential energy because it has the greatest height from the ground. GPE = mgh, increasing the h increases the GPE.
