One object has a velocity of -4 feet per second another has 3 feet per second which is greater?

The object with the velocity of -4 feet per second is going faster than the other, but in the opposite direction, hence the minus sign.

An object traveling at a constant 20 miles per second in a circular path is changing what?
This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.
What is the velocity of a ball thrown at 16 feet per second?
16 feet/second is the speed. To know the velocity, you would also need to specify the direction in which the object moves.
What does and acceleration of five meters per second squared mean about the velocity of the object?
It means that the object's speed is always 5 meters per second faster than it was one second earlier.
How can height affect the time for an object to fall?
The acceleration of gravity is 32 feet per second, per second. This means that --eliminating any obvious aerodynamic considerations as there would be with, say, a feather -- the speed at which an object falls increases proportionately to the time it is falling. An object falling from a greater height will be falling for a longer time period and thus will reach a higher velocity and impact the ground with a greater force than one falling from a lower height.
What object shoots upward with an initial velocity of 6 meters per second?
anything shot up with that initial velocity. There isn't anything in specific.
Is the tangential velocity of a rotating object greater when it is close to the center of rotation or when it is far from the center of rotation?
The tangential velocity is greater as the radius of the point on the rotating object increases. For a rotating object v = rw Where v is the tangential velocity r is the radius of the point And "w" is omega or angular velocity (in radians per second)
How do you calculate the change in velocity of a falling object?
The speed (magnitude of velocity) is always 9.8 meters per second (32.2 feet per second) greater than it was exactly one second earlier. If the object spent "N" seconds falling, then its speed (magnitude of velocity) is 9.8N meters per second (32.2N feet per second) greater at the bottom than it was at the top. The direction of velocity remains constant under the influence of gravity ... straight down.

What happens to the mass of a speeding object in space?
Recall a fundamental postulate of relativity -- that one can not define the velocity of an object except in reference to a frame. Thus, we can NOT say an object is "speeding" unless we also define against which frame we are making measurements. In an object's own frame, its own mass never changes. In a frame that views such an object as "speeding," the mass of the object will be greater than it is in its own frame. Not "mistaken to be" greater, not "viewed as" greater, not "seems to be" greater, not "appears to be" greater. The mass IS greater in that second frame.
What is the deffinition of velocity?
Velocity is the speed of an object in a given direction. It is typically measured in meters/second.
What happens to an object in free fall as it reaches terminal velocity?
every second the velocity increases by 9.8m/s per second per second
If an object starts to accelerate?
If an object moved with constant acceleration it's velocity must ?
What is the gain velocity per second for a freely falling object?
Impact velocity depends on the mass of the object and the height it falls from. It is the speed at which the acceleration due to gravity is maximized.
What is the final velocity of a freely falling object?
The final speed of an object in free fall is known as terminal velocity. Terminal velocity on Earth can range from 54 meters per second (in SI units) to 90 meters per second based on aerodynamics.
What is change in the velocity of a falling object?
Any change in the velocity of anything is known as 'acceleration'. In the case of a falling object near the Earth's surface, the direction of the velocity is constant, and its magnitude increases by 9.8 meters (32.2 feet) per second, every second.
What is the acceleration of an object?
When a net force acts on that object, there is a change in velocity, and thus acceleration.
What is required to change velocity of an object?
In order for an object to travel with constant velocity the sum of forces acting on it must be 0 N. According, to Newton's second law, ΣF = ma where ΣF is the sum of forces m is mass a is acceleration If the acceleration is not 0, then the object is not traveling at a constant velocity. In order for a to equal 0, the sum of forces must be 0 because by solving Newton's second law for a, we get a=ΣF/m If ΣF is not 0, then that equation will never allow a to equal 0 and the object will b accelerating. Therefore, the sum of forces must equal 0 for an object to travel with constant velocity.
