Deceleration (or negative acceleration).
1 milimeter long is an example of a mesurment less than 1 centimeter.
There are infinitely many numbers less than 6.59. -3, for example.
How about 11 as one example
If the numerator is less than the denominator, the fraction is less than one. For example, 5/7 is less than one. If the numerator is greater than the denominator, the fraction is greater than one. For example, 10/7 is more than one.
x is equal to or less than -3 means that x is every number from -3 onwards all the way to negative infinity. For example, -4 would be less than -3, -5 would be less than -4 which is less than -3 and so forth. So for the final answer, the interval of x that is equal to or less than -3 would be written like this: (-inf,-3] There is a parenthesis on negative infinity because it is impossible to reach infinity and since x is equal to -3, we put the brackets to indicate that the -3 is included in the interval.
positive acceleration
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.
i think it's 2
Negative acceleration.
inital velocity (u) should be less
increasing speed
Reduced atmospheric drag at higher altitudes, Acceleration due to the thrust of the rocket's engine(s).
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.
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.
Its initial speed is less than its final speed.
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
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)
