How do forces affect acceleration

As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work. The greater the mass the greater the amount of force needed to accelerate the object. More force is required to move a heavier object than a lighter object.

It is an inverse relationship. In an inverse relationship, when one variable increases, the other variable decreases.

The greater the mass of an object, the less it will accelerate when a given force is applied. The greater the force, the greater the acceleration. The greater the mass, the less the acceleration.

This is relevant to walking because when you put your foot on the ground, you are applying a force to it. In doing this, the ground also actually applies an equal force onto your foot, in the opposite direction, pushing you forward. The Third Law states that for every action force, there is an equal and opposite reaction force.

The two forces create an interaction pair on different objects and are equal in strength and opposite in direction. Regardless of differences in mass, all objects accelerate at the same rate due to gravity unless air resistance affects one more than another.

It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed. Therefore, heavy objects will fall faster in air than light objects. But they can increase their speed tremendously by orienting their head towards the Earth — diving towards the ground.

Terminal velocity is the fastest that an object will ever fall, no matter what height it is dropped from.

Squirrels unlike most other mammals can survive impacts at their terminal velocity. Which means no matter what height you drop a squirrel from, it will probably survive. Objects falling through a fluid eventually reach terminal velocity. At terminal velocity, the object moves at a steady speed in a constant direction because the resultant force acting on it is zero.

Highly unlikely. According to myth, a penny dropped from the Empire State Building can kill someone below. Apparently the myth is simply not true. A penny only weighs about a gram and it tumbles as it falls. So yes, ants do get sad and respect others. It shows that the new study tells ants deal with their dead much like humans.

The terminal velocity for an ant in air is quite small — no more than two meters per second, I guess having dropped a number of ants from about a meter myself. Ants are also amazingly durable — they have very hard exoskeletons. Mice can survive any fall: their terminal velocity is slow enough. Mice, and also rats, survive falls down mine shafts. Cats are at the borderline.

As far as entomologists are concerned, insects do not have pain receptors the way vertebrates do. Table of Contents.
