Is 0 velocity and 0 acceleration correctly describes the velocity and acceleration of the rock at the exact top of its path?
No. Any object that was shot by gun, flung by slingshot, or thrown by hand, begins accelerating
downward at the acceleration of gravity as soon as it leaves the propulsion system.
Zero velocity is true at the top, but acceleration is constant throughout the trajectory ... 9.8 m/s downward.
What else can I help you with?
Instantaneous acceleration describes how fast a is changing at a specific instant.?
Yes, instantaneous acceleration is the rate at which an object's velocity is changing at a specific moment in time. It gives information about how quickly the object is speeding up or slowing down at that exact instant.
What is instantaneous acceleration'?
Instantaneous acceleration is the rate of change of velocity of an object at a specific moment in time. It provides information about how quickly the velocity of an object is changing at that exact instant. It is a vector quantity, meaning it has both magnitude and direction.
What is the velocity of a ball dropped on the surface of Mars if the acceleration of gravity is 3.7 meters per second squared?
When given a constant acceleration, just multiply it by time, t, to detemine the final velocity. If the initial velocity was zero (as is the case when you drop something), then the average velocity is half the terminal velocity.
Does the Magnitude of a charge affect the velocity of body?
That depends on the exact situation. If there is an interaction with other charges, this can cause the object to acceleration (basically, change its velocity), and the greater the object's charge, the faster its velocity will change.
Is instantaneous velocity the right answer to the question speed and direction of an object at a specific moment?
No, instantaneous velocity is the correct term for the speed and direction of an object at a specific moment. It describes how fast and in which direction an object is moving at an exact instant in time.

When an object is thrown straight up at the highest point the downward velocity is?
A rock has the same constant acceleration from the moment it leaves your hand until the moment it hits the ground. It doesn't matter whether you dropped it or threw it, or in what direction it left you. The acceleration is 9.8 meters (32.2 feet) per second2 directed downwards. That's the acceleration of gravity on earth. As you asked, let's say you tossed it straight upwards. A tiny instant before it reaches the exact top, it has a small upward speed. A tiny instant after it passes the exact top, it has a small downward speed. During that tiny space of time, its upward speed decreases and its downward speed increases. That's a downward acceleration in anybody's book.
The slope of a line drawn tangent to a point on the curve of a position vs time graph describes what concept?
The slope of a line drawn tangent to a point on a position vs. time graph represents the instantaneous velocity of the object at that point. It describes how the position of the object is changing at that exact moment in time.

That depends on the exact situation. If there is an interaction with other charges, this can cause the object to acceleration (basically, change its velocity), and the greater the object's charge, the faster its velocity will change.
Can an object's velocity change direction when its acceleration is constant?
No. Acceleration is a change of velocity and doesn't have to point in the same direction. Consider braking car: it still moves with decreasing velocity in one direction, while braking force and thus acceleration is in the opposing direction.
Is instantaneous velocity the right answer to the question speed and direction of an object at a specific moment?
No, instantaneous velocity is the correct term for the speed and direction of an object at a specific moment. It describes how fast and in which direction an object is moving at an exact instant in time.
What is the detonation velocity of an atomic bomb?
In excess of 50,000 meters/second, but the exact velocity depends on yield.
Can an object have zero velocity and non-zero acceleration?
Yes, an object can have have zero velocity and non-zero acceleration. This happens when an object is at rest and when a force is applied on it such as gravity. But this isn't always true. A good example of another situation is when you throw an object vertically up into the air. Such an object will be acted upon by the constant acceleration of gravity. Due to this acceleration, it will slow down, then it will reverse direction, and finally it will fall back to the ground. At the exact point at the top of its path before falling back down, the object will have zero velocity. Yet it will still be accelerating towards the ground the whole time. The object is being accelerated by the force of gravity throughout its entire journey.
