According to Newton's law.
Force = mass x acceleration. If you know the force acting upon an object and the mass of the object you can easily calculate the acceleration it will experience.
There are a few. The most famous is a = F/m, where F is the net force applied to a mass, m.
Acceleration is also the change in velocity, (Delta-V), divided by the change in time, (Delta-t). So, a = Δv/Δt.
Acceleration is calculated as the change in speed over
To calculate acceleration, divide the change in speed by the time during which the acceleration occurs. :)
You need the speed and velocity +++ They are equivalent save that speed is a scalar and velocity a vector. You need intervals of time and distance.
force and mass. acceleration=force divided by mass or the time, final velocity, and initial velocity. acceleration= final velocity minus initial velocity diveded by time
The initial and final velocities and time taken for the change to happen. Alternatively, if you know the object's mass and the force applied to it you can compute acceleration as a = f/m.
Any distance in time squared.
Speed and time. As acceleration is the change in speed over time.However, if you do not have a direct reading of speed, you will need to claculate that also, from distance over time.So all the units are:-Distance = MetresTime. = SecondsSpeed = m/sAcceleration = m/s/s or m/s2
You may see acceleration mentioned in a momentum problem; but if it's there, it's only purposeis to help you find the object's velocity.All you need to know in order to find momentum is the object's mass and velocity.
its acceleration will be increased
Weight is a force equal to the product of an object's mass and gravity. Gravity in this context is not a force but an acceleration. Near the Earth's surface, that acceleration is 9.8 m/s², regardless of the mass.
You need to know its mass and multiply that mass by 9.8. Mass = mg . m= mass, g = 9.8 m/s
This is imposible to calculate. In order to find acceleration, knowlege of at least 3 of these variables must be given: initial speed, final speed, distance, and time.
The object's instantaneous acceleration is (8t - 8) at any time.We can't calculate the average acceleration, because you haven't defined a periodof time over which to average it. We need the start and finish times in order tofind an average.
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.

A pair of coordinates
its acceleration will be increased
You need to measure it. You cannot calculate it from the available information.
Acceleration must occur. Otherwise, the item is going from 0 to something in 0 time, which means infinite acceleration (v/t) and in turn, infinite force, which is practically impossible.

If net force acting on a mass decreases, the acceleration of the object decreases. But if the mass of an object were to decrease while a constant net force acted on it, its acceleration would INcrease. If the net force on the object AND the object's mass both decrease, the object's acceleration could either increase OR decrease. We'd need the actual numbers in order to calculate how it would turn out.
