Zero g forces give the feeling of weightlessness. It is not a certain speed that gives the feeling of weightlessness, but the change in the amount of gravity.
To effectively solve equilibrium equations, one must first identify all the forces acting on an object and their directions. Then, apply the principles of equilibrium, which state that the sum of all forces and torques acting on an object must be zero. By setting up and solving equations based on these principles, one can determine the unknown forces and achieve equilibrium.
Velocity is relative to the observer and or objects that are in the area , if your sitting in true zero gravity from your point of view you will be standing still but in-reality your velocity will based on your original thrust. Some one watching you (at a zero velocity) from another location might see you zoom by at the original velocity. So the new question is if that other person has zero velocity and is in zero gravity what time will it be when they look at their watch ? Hmmm
In that case, the vector sum of the forces is zero; the forces are said to be balanced. You can also get balanced forces with more than two forces, for example, three forces of the same magnitude at an angle of 120 degrees to one another.
Sure. -- Three forces all pointing north, each of them = 10 pounds. -- Two forces both pointing south, each one = 15 pounds. or -- One 10-pound force pointing north, one east, one west. (Three forces.) -- Two forces both pointing south, each = 5 pounds. There are an infinite number of ways to arrange five forces with the same or different magnitudes, in different directions such that their vector sum is zero.
One force is never "balanced". The word describes the overall combination of two or more forces. The whole group of forces is said to be balanced if their vector sum is zero. Example: The forces of two people pulling on a rope are balanced if their forces add to zero and the rope doesn't move. It's called a "Tug of War".
Consider two equal and opposite forces acting along different lines of the body, which causes the body to rotate, although first condition is fulfilled but body is still moving. Thus, we need another condition for equilibrium that is the second condition of equilibrium.
Why not ? Take four big guys shaped like barrels, who can push a car uphill with one hand. Now put the car on a flat parking lot and spread the four guys around it, with one guy in the back pushing forward, one in the front pushing backward, one on the left pushing right, and one guy on the right pushing left. Where will the car go ? Nowhere. Even in neutral with the parking brake off. If you remember to include the directionof each force, then all the forces on the car add up to zero.
No. For equilibrium, the SUM OF ALL FORCES acting on an object must be zero, and that is not possible with a single (non-zero) force.Note: For equilibrium, the sum of all torques on an object must ALSO be zero.
There's no such thing as one single balanced force. A group of two or more forces are balanced if they all add up to zero. Like if two people are pushing on the same shopping cart ... one in the back pushing it forward, and one on the front pushing it backward. They add up to zero, and the cart acts exactly as if there are no forces on it at all ... it stands still. Those two forces are balanced.
That means that there are one or more forces acting on an object, but the vector sum of these forces is not zero. That would cause the object to accelerate - in other words, its speed would change.
Most Superbikes are capable of zero-to-sixty in approximately 3.5 seconds. Zero-to-one hundred usually takes around 4-5 seconds. Accelleration decreases as the engine nears its' top speed, but in 10 seconds, a superbike will normally have reached around 200-220mph. Moto-GP bikes are capable of the same zero-to-sixty and zero-to-one hundred speeds, but have slightly lower top speeds. In 10 seconds, a Moto-GP bike will have reached about 180-200mph. Road-bred sportsbikes are slighly slower on the accelleration (Zero-to-sixty in 4-5 seconds, zero-to-one hundred in 7-9 seconds) but have top speeds comparable to those of Moto-GP bikes. 10 seconds will take most road bikes to around 160-180mph. Note: "Superbike" in this answer denotes race-bred motorcycles of 900-1000cc. "Moto-GP" denotes race bred motorcycles with engines between 500 and 650cc. "Road-bred" means bikes with engines larger than 500cc that are designed for legal road use.
The vector sum of the forces must be zero for an object to be in equilibrium when acted upon by a number of parallel forces. This means that the forces are balanced and there is no net force acting on the object in any direction.
