What effect does gravity have on the mass of an object?
Gravity has no effect on the mass of an object. However, an object's weight is the measurement of gravitational force on the object. The gravitational force on the moon for example is ~ 1/6 of that on Earth. A 300 kg object would weigh 3000N (Newtons) on the Earth but only weigh 500 N on the Moon but its mass would still be 300 kg on the Moon and on the Earth.
What is the pressure exerted on the floor by a 3000N crate with an area of 2m squared?
Pressure is the force on something per unit area. P = F/area If using SI units (which we are) then it's measured in Pascals (N/m(sq)) Assuming your crate is applying it's force evenly and that it is on a flat floor then it's just 3000/2 = 1500 Pa. Fun to be had tipping your crate up onto a corner (say about a cm square in contact) so it then produces a force of 3000/0.01 = 300,000 Pa This is why thin girls in stiletto heeled shoes leave marks on floors....
What is the mass of an object that is accelerating at 15ms when a force of 3000N is exerted?
45000 m/ s squared
What force is needed to give a 2000 kg car an acceleration of 1.5 m cubed?
F = M a = (1,300) x (1.5) = 1,950 newtons
A car is moving at a constant speed of 30ms the combined mass of the car and the driver is 1000kg if the driving force is 3000N what is the value of the frictional force?
If the car and driver are moving (along a flat horizontal surface) at constant speed, then there is no acceleration, and the net horizontal force is zero.The applied 3,000N must be canceled by an effective total 3,000N of friction.

How many newtons is 3000 pounds?
For an object experiencing a constant net force, Newton's Second Law of Motion can be used to obtain the equationF = ma,where F is the net force, m is the mass of the object and a is the acceleration of the object due to the net force, F. Rearranging the equation for acceleration and substituting in the mass of the box and the net force acting on it givesa = 900N/300kga = 3ms-2.
Force mass multiplied by acceleration .....how much force is needed to accelerate a 1000-kg car at a rate of 3 meters per second squared?
Well force=mass x acceleration. Force in Newtons (N) Mass in kg Acceleration in metres per second squared. force = 3000N 3,500 N
