Answer 1:
Heavy objects fall at the same rate (or speed) as light ones
. The acceleration due to gravity is about 10 m/s
2
everywhere around earth, so all objects experience the same acceleration when they fall.
Do objects with more mass fall faster?
Heavier things have
a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
What controls how fast an object falls?
A: How fast something falls due to gravity is determined by a number known as
the “acceleration of gravity”
, which is 9.81 m/s^2 at the surface of our Earth. Basically this means that in one second, any object’s downward velocity will increase by 9.81 m/s because of gravity.
What is the acceleration of an object in free fall at Earth’s surface quizlet?
The acceleration of gravity upon Earth’s surface is
9.80 m/s/s
.
Why do lighter objects have more air resistance?
The air is actually an upward force of friction, acting against gravity and slowing down the rate at which the feather falls. … Galileo discovered that objects that are more dense, or have more mass,
fall at a faster rate than less
dense objects, due to this air resistance.
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?
So all objects, regardless of size or shape or weight,
free fall with the same acceleration
. In a vacuum, a beach ball falls at the same rate as an airliner. … The remarkable observation that all free falling objects fall with the same acceleration was first proposed by Galileo Galilei nearly 400 years ago.
What forces act on an object in free fall?
When the only force acting on an object is
gravity
, the object is said to be in free fall. The force of gravity causes the object to accelerate. Free fall is motion where the acceleration is caused by gravity. When something falls on Earth, there is fluid friction from the air around it.
What controls how fast an object falls quizlet?
Gravity
causes all objects to accelerate toward Earth at a rate of 9.8 m/s/s. Air resistance slows the acceleration of falling objects. An object falls at its terminal velocity when the upward force of air resistance equals the downward force of gravity.
Do resting objects have inertia?
Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position.
All objects have inertia
. … Inertia is the tendency of all objects to resist motion and ultimately stop.
Which object is most affected by air resistance?
Both
elephant
and feather have the same force of gravity, yet the feather experiences a greater air resistance. Each object experiences the same amount of air resistance, yet the elephant experiences the greatest force of gravity.
Why do 2 objects fall at the same time?
Because that object feels a force,
it accelerates
, which means its velocity gets bigger and bigger as it falls. … Because Earth gives everything the exact same acceleration, objects with different masses will still hit the ground at the same time if they are dropped from the same height.
What falls faster an elephant or a mouse?
True or False? Free body diagrams of the Elephant and Mouse show that the mouse quickly reaches terminal velocity, (Terminal Velocity occurs when Fg = Fair) while the elephant continues to accelerate for much longer. The elephant is therefore going
faster when it hits the water
.
Do objects hit the ground at the same time?
Gravity is the force that causes things to fall to earth. When you drop a ball (or anything) it falls down. Gravity causes everything to fall at the same speed. This is why
balls that weigh different amounts hit the ground
at the same time.
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.
What happens when you hit the ground at terminal velocity?
In very high falls, bodies can reach terminal velocity, the
speed at which air resistance becomes so high it cancels out the acceleration due to gravity
. Once at terminal velocity, you can fall as far as you like and you won’t gather any more speed.
