Why do two objects hit the ground at the same time?
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. Gravity is the force acting in a downwards direction, but air resistance acts in an upwards direction.
What explains why two objects of different sizes hit the ground at the same time when dropped from the same height?
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. The less massive the object is, the more the force of air resistance slows the object down as it falls.
Why do objects hit the ground at the same time in a vacuum?
In other words, the mass of the object cancels out in the mathematics and the acceleration is a constant. So, the acceleration due to gravity is independent of mass. So heavy and light objects fall to the ground at the same rate in a vacuum, where there is no air resistance.
Why do two objects of different weight fall at the same speed?
Acceleration of Falling Objects 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 do you observe when you push the 2 same objects at the same time with the same force?
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
Does two objects fall same time?
If no air resistance is present, the rate of descent depends only on how far the object has fallen, no matter how heavy the object is. This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height. In air, a feather and a ball do not fall at the same rate.
How it is possible for two objects having different size and mass fall at the same rate when dropped at a certain height?
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.
How do two objects of different masses fall in a vacuum chamber compared to falling through the air?
The mass, size, and shape of the object are not a factor in describing the motion of the object. 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.
Why do objects fall at the same rate on the moon?
This air causes friction with objects as they fall through it, called air resistance, which can slow them down as they fall. Because the Apollo crew were essentially in a vacuum, there was no air resistance and the feather fell at the same rate as the hammer.
What happens when two objects of different masses are dropped from the same height?
If two objects of different masses are dropped from the same height at the same time in a vacuum, they will reach the ground simultaneously. In other words, the rate at which objects accelerate towards the surface of the earth is independent of the objects’ weight.
What happens when two objects with the same mass collide?
When two objects with the same mass collide, Newton’s laws tell us that they will accelerate the same amount but in opposite directions. Recall that force, velocity, and acceleration have both magnitude and direction. We use positive and negative signs to indicate the direction of each of these quantities.
