When velocity is zero and acceleration is less than zero does the speed increase?
if acceleration is <0 and velocity =0 then you got the handbrake on
What is necessary to accurately and completely describe the motion of an object?
To completely describe the motion of an object you will need to know (1) the object's position in space and time, (2) the objects velocity, including the direction of travel, and (3) the object's acceleration, including the direction of acceleration. However, the Heisenburg Uncertainty principle states that the more accurately you measure object's position, the less information you will have about its velocity, and vica versa. The more accurately you measure an object's velocity, the less information you will have about its position.
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
increasing speed
Is the amount of acceleration directly proportional to the fore and to the mass?
No, an object's acceleration is inversely proportional to an objects mass.
Why is the acceleration is faster in small objects than in large objects?
The difference is due to inertia. Inertia is the resistance to a change in motion (acceleration). A more massive object will have greater inertia, and therefore a greater resistance to a change in motion, resulting in a slower acceleration. A less massive object has lower inertia, and therefore less of a resistance to a change in motion, resulting in a faster acceleration.
When an object's final velocity is less than its initial velocity it has what kind of acceleration?
Negative acceleration.
When final velocity is less than initial velocity is an example of?
Deceleration (or negative acceleration).
Which is greater in positive acceleration initial or final velocity?
inital velocity (u) should be less
A rocket ship leaves earth's atmosphere its initial velocity is less than its final velocity which is this an example of?
positive acceleration
A rocket ship leaves the earths atmosphere its initial velocity is less than its final velocity this is example of?
Final velocity vf is greater than the initial velocity vi . That is vf > vi . This is an example of acceleration (positive). Average acceleration aav = [vf - vi]/[tf - ti] where ti is initial time, and tf is final time.
When an object's initial velocity is less than its final velocity what does that indicate?
AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
An objects acceleration decreases as the objects mass?
force = mass * acceleration then mass and acceleration is inversly proportional. Actually mass is constant but when the speed increases the mass become less since acceleration and velocity is directly propotional thus acceleration increases too.....thx..with best regards..
How do you calculate deseleleration?
Deceleration (not deseleration) is the negative rate of change of velocity over time. Acceleration is [Final velocity - Initial Velocity]/Time. If the final velocity is less than the initial velocity, then the above quantity is negative and is termed deceleration. The instantaneous deceleration is dV/dt, the derivative of the velocity with respect to time. Sometime acceleration and deceleration are defined in terms of speed rather than velocity. This is not correct since it is inconsistent with the laws of motion.
When final velocity is less then initial velocity of an object the acceleration is negative?
yes, many answers in applied maths come out as negative, it just means that the force or object is slowing down or reversing. in this case there is a negative acceleration as its slowing down
When velocity is zero and acceleration is less than zero does the speed increase?
if acceleration is <0 and velocity =0 then you got the handbrake on
A rocket ship leaves earth's atmosphere. Its Initial velocity is less than its final velocity. What is this an example of?
Reduced atmospheric drag at higher altitudes, Acceleration due to the thrust of the rocket's engine(s).
What is initial velocity if its less than final velocity?
i think it's 2
