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
Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non zero.
Yes, it is possible for an object to be traveling with a non-zero velocity even if it is experiencing a net zero external unbalanced force. This is because the object may have inertia, which allows it to maintain its current velocity unless acted upon by an external force.
Absolute velocity refers to the speed and direction of an object relative to a fixed point, regardless of any external factors. In the context of a free falling body with zero net force due to air resistance and gravity, its absolute velocity would be constant and equal to the velocity just before air resistance became negligible.
Yes, it is possible for the average velocity of an object to be zero during a given interval even if its average velocity for the first half of the interval is not zero. This can occur when the object moves in opposite directions such that the distances traveled cancel out over the entire interval. For example, if an object moves 3 meters to the right and then 3 meters to the left in equal times, its average velocity for the entire interval would be zero.
Yes, it is possible for a body to have zero velocity while experiencing non-zero acceleration. This occurs when the body is changing direction but not speed, such as in circular motion. Another example is when the body is momentarily at rest at the peak of its motion, like a ball thrown upwards.
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non zero.
Yes, but only for a single instant in time. When you throw a golf ball or a rock straight up, it has the constant downward acceleration of gravity from the moment it leaves your hand, but its velocity is certainly not constant. The velocity steadily decreases until the peak of the toss, and then it switches from upward to downward velocity. At the very peak, the velocity is zero for an instant.
Yes, it is possible. When a body thrown upward (from the surface of Earth or any other planet but with velocity small enough not to overcome the gravity) and reaches its maximum elevation its velocity is zero but the acceleration is g (due to gravity).
Yes, satellite orbiting the Earth in a Geo-Stationary Orbit has 0 Velocity relative to a point on the Earth, BUT it experience the 'Pull' (acceleration) of Gravity, which prevents it from escaping its Orbit. The Gravity is LESS than that at the surface of the Earth, but not 0. The feeling of WEIGHTLESSNESS is not due to Zero Gravity, but due to the fact that Object is FALLING through its Orbit. A Person Falling "feels" Zero Gravity.
No,because if the car is moving at a constant velocity that means the acceleration is zero. So the net force is zero and there may be some forces acting on it. Only gravity, downward.
There is no "zero gravity" place. Gravity permeates all the universe. Astronauts in orbit are often said to be in zero gravity but they are, in reality, on a position where their orbital velocity balances the attraction of the Earth.
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
No.
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
In zero gravity, an object will typically stay in place if it is not acted upon by any external forces. If an external force is applied, the object may move in the direction of that force. Objects can float or move about freely in zero gravity depending on their initial state.
