The force of the surface of the Earth on the soles of your feet that keeps you from entering an elliptical orbit like Caroline, makes it appear that she is accelerating... because we are enculturated to ignore the facts. Also known as "lithospheric friction". Newton described "gravitation" or "gravity" but he was never happy with "action at a distance". Einstein showed that no such action is required. Caroline conserves 4-momentum.

An unbalanced force can cause an object to change its speed and or?
The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. ... If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.
What connection did newton make between the moon and a falling apple?
the moon pulls waves with a force pulling up or rising the waves
Does the acceleration produced by the force on a given mass depend on the time of action of the force?
That simply means that if you apply more force, it will accelerate (for example, speed up or slow down) faster. "Net force" is the vector sum of all the forces acting on an object.Acceleration also depends on the mass.
Newton figured out that the force that made an apple fall from a tree was the same as the one keeping the Moon in orbit around Earth?
The legend is that Newton made the connection between the 2 questions when he watched the falling apple ........... Newton realized that the same unbalanced force affected the motions of the apple and the moon.It all has to do with gravity. The moon pulls the waves with the force pulling up or rising the waves, well the apple is brought to the ground with the force or the gravity on Earth.Legend says that Newton, said that the force that made the apple fall from the tree, makes earth fall from the sun and the moon fall from the earth. This force operates throughout the Universe and is a Universal Force..
A force can cause an object to change its speed and or direction?
A force can cause an object to change its speed or direction. A force causes acceleration, as given by Newton's equation F=ma, where f is force, m is mass, and a is acceleration. Acceleration occurs when something either changes direction, like a tether ball is accelerating when it goes around the pole, or when the objects speeds up or slows down.Forces give energy to the object it is acting on.The more mass an object has, the harder it is to move, stop, or change the speed or direction of the object.An object will not start moving unless a force acts on it.An object will not stop moving unless a force acts on it.An object will not change speed unless a force acts on it.An object will not change direction unless a force acts on it.unbalanced
What force causes falling things to Speed up?
Gravity
What is a non contact force that makes something speed up?
Gravity.
Why is gravity a bigger force than air resistance?
It isn't, necessarily. But the force of gravity is constant, whereas the force of air resistance depends on how fast you're moving through the air. So when you begin to fall, gravity is stronger, and it makes you fall faster and faster. But as your speed increases, so does the force of air resistance, and eventually, the force of air resistance builds up to be equal to the force of gravity. At that point, you keeep falling, but your speed doesn't grow any more.
What force that pulls you up when falling?
reaction
How do engineers force a roller coaster to speed up?
How do engineers force a roller coaster to speed up
When an object is falling toward earth what force is pushing up on the object?
Because of force
The greatest velocity a falling object reaches is terminal?
When an object is not accelerating or decelerating, it has a net force of zero.
What do balanced forces acting on an object really cause the object to do?
If an object is falling, and the gravitational force is the same as the air resistance acting against the object it is called terminal speed, the object does not speed up, nor slow down A balanced group of forces has the same effect on an object as no force at all.
A force causes a mass to?
speed up
Is it possible for the opposing magnetic field to be strong enough to completely stop an object from falling?
No because the magnetic field induced attracts the falling magnet, creating a force which slows down the magnet. If the magnetic field increased to a certain point where the force acting on the magnet was enough to stop the magnet from falling, gravity would act on the bob, causing the magnet to speed up again until it reaches a happy medium speed (or even a terminal speed if you will). When this happens, a changing magnetic field occurs and an induced current is formed again. This cycle repeats.
When a falling object stops speeding up and falls at a constant rate of speed that object has reached its?
terminal speed
How are height distance and speed related?
Now, this is in very....basic. It also may not be 100% correct. The higher up you are, the more distance you fall. The more distance you fall, the faster you go. You peak at a certain speed, and will continue falling at that speed once it is reached. The max speed differs in the amount of weight falling. (Proven by an Egg falling, or a Feather falling.)
