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.
What else can I help you with?
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..
Truefalse can friction slow things down?
true. Friction DOES slow things down. In fact, if there was no friction once something started moving it wouldn't be able to stop Friction can slow the things down. It's true.
What is the direction and magnitude of the net force acting on a rain drop falling down with constant speed?
If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.
Why do falling objects speed up as they fall?
Falling objects speed up due to the acceleration of gravity. As an object falls, the force of gravity causes it to accelerate towards the Earth at a rate of 9.8 m/s^2. This acceleration increases the object's speed over time.
When a falling object stops speeding up and falls at a constant rate of speed that object has reached its?
When a falling object stops speeding up and falls at a constant rate of speed, it has reached its terminal velocity. Terminal velocity occurs when the force of air resistance equals the force of gravity acting on the object, resulting in a balanced and constant downward acceleration.
What causes falling objects to speed up as they fall?
Falling objects speed up due to the acceleration of gravity acting on them. As an object falls, the force of gravity pulls it downward, causing it to accelerate. This acceleration causes the object to increase in speed until it reaches terminal velocity or hits the ground.
What causes an object to slow down or speed-up?
an external net force acting on it
How do engineers force a roller coaster to speed up?
How do engineers force a roller coaster to speed up
What force that pulls you up when falling?
When falling, the force that pulls you up is called the normal force. This force is exerted by a surface (such as the ground) in reaction to the force of gravity pulling you downward. The normal force acts perpendicular to the surface and prevents objects from passing through it.
When will an object stop falling toward earth stop accelerating?
at terminal velocity
When an object is falling toward earth what force is pushing up on the object?
When an object is falling toward Earth, the force pushing up on the object is gravity, which is pulling the object downward towards the Earth's center. There is no active force pushing the object up as it falls.
What is a non contact force that makes something speed up?
One example of a non-contact force that can make something speed up is gravity. When an object is in free fall, gravity pulls it downward, causing it to accelerate and increase in speed. Another example is magnetic force, where two magnetic objects can repel or attract each other, causing one object to speed up towards the other.
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 is the net force acting on a falling object when it reaches terminal velocity?
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
