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).
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.
How do you find work given mass initial velocity and final velocity?
We assume you mean the work done in order to change the velocity of the moving mass.Easiest way is to calculate the change in the kinetic energy of the moving mass, and realizethat it's equal to the amount of work either put into the motion of the mass or taken out of it.Initial kinetic energy = 1/2 m Vi2Final kinetic energy = 1/2 m Vf2Change in kinetic energy = 1/2 m ( Vf2 - Vi2)
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
What is dimensional equation?
A dimensional equation is one in which the units of measurement and their powers are used rather than their actual numeric values. For example, consider an object under constant acceleration: let u denote its initial velocity v denote its final velocity a the acceleration and t the time between the initial and final points of time. Then v = u +at The dimensional equation is [LT-1] = [LT-1] + [LT-2][T] L represents a dimension of length T represents a dimension of time M, which does not appear here, would represent mass. Only terms with the same dimensions may be added or subtracted.
When final velocity is less than initial velocity is an example of?
Deceleration (or negative acceleration).
When an object's final velocity is less than its initial velocity it has what kind of acceleration?
Negative acceleration.
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
increasing speed
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.
If final velocity is greater than initial velocity an object is?
Accelerating...or was accelerating.
How will the final velocity be greater then the initial velocity?
It doesn't necessarily mean that the final velocity is always greater than the initial, if the initial velocity was at rest or 0 m/s then any form of movement would be greater. In cases where the final is smaller is like running into a wall or a decrease in acceleration.
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.
If a car is speeding up its initial speed is what than its final speed?
Its initial speed is less than its final speed.
