Does an object at rest have forces acting on it and if so what forces would be along the vertical axis?
All objects on earth have the force of Gravity acting on them.
The force that pulls falling toward earth is called?
The force that pulls an object toward earth also pulls the earth toward the object. The two forces are equal. Together, we refer to them as the forces of gravity.
The motion an object experiences when it falls toward the earth with no forces acting upward?
Free Fall
What can you say about the forces acting on a stationary object?
The forces acting on a stationary object are balanced. If you were to add up all the forces (taking the directions into account, you would get a total of 0. There are always forces acting on a object, such as gravity, so you cannot say that there are no forces acting on it. You can say that the forces are balanced.
The force of gravity acting upon the mass of an object?
That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.
Is the force of gravity expierenced by an object fifty miles above the earth the same as if it were on the earth?
No. However at that altitude, it is likely there are some forces of acceleration acting on the object which will affect it.
What are some of the force that effect an object on earth?
On earth, the forces acting on any object is gravity. Since there is an equal and opposite reaction to any force, the earth pushes back on the object. This is called the normal force.
9.81 ms2 What does this measure and is it always true?
9.81 m/s2 is the acceleration of an object in free fall, responding only to gravity with no other forces on it, on or near the Earth's surface ... otherwise known as the acceleration of gravity. It's always true on or near the surface of the Earth ... if you can provide those conditions: No other forces except gravity acting on the falling object, including no air resistance !
Does an free falling object has an frictional effect?
To be very technical and precise, the answer consists of two parts: 1). No. 2). Outside of laboratory conditions, there can be no free-falling objects on Earth. "Free falling" means that there is no other force on the object except the gravitational one, so there's no friction acting on it. But this situation is impossible on Earth, because anything that falls is falling through air, so it does have friction acting on it ... called "air resistance" ... and it's not free falling.
Is there any force acting on an object which is falling freely?
Yes. The definition of "free fall" implies that gravity from Earth - or perhaps from different objects - is acting on the body.
What opposing forces act on an object falling freely through the atmosphere?
The forces that affect the rate of a falling object are Gravity and Air Resistance. Gravity affects the speed and the velocity of the object by speeding it up as it falls closer to the earth, and Air resistance works against the object pushing against it.
For an object to be in projectile motion what force must be acting on it?
Other than what?A falling object will be attracted by Earth; this will tend to make the object fall faster and faster. Another force is the force of friction which will tend to slow the objec tdown. At terminal velocity - after falling a while - the two forces are in equilibrium.
