Why are the objects easier to push or pull than others?
An object with a greater mass needs more force. Mass is what gives an object resistance to acceleration. Newton's Third Law: force = mass x acceleration, or acceleration = force / mass.
What law of motion explains why a pingpong ball accelerates faster than a golf ball when hit with the same force?
Force = (mass) x (acceleration) Acceleration = (force) / (mass) With the same force applied, a smaller mass has greater acceleration. A baseball has less mass than a shot has, so the same force gives it greater acceleration.
How does the direction of acceleration compare with the direction of the net force that produces it?
Acceleration is proportional to net force.That means that acceleration is equal to (net force) times (something).The 'something' is [ 1 / (the mass of the object being accelerated by the force) ].
An unbalanced force of 30 N gives an object an acceleration of 5. What force would be needed to give it an acceleration of 1?
If a force of 30 N imparts an acceleration of 5 to an object and we desire only one fifth of that acceleration, then we apply only one fifth of that force. Take the 30 N and divide it by 5 and we find that 6 N is the force required to give our test object an acceleration of 1.
How is constant velocity and equilibrium related?
Constant velocity gives zero acceleration, force is mass times acceleration, thus if acceleration is zero then force is zero and equilibrium is zero force. Equilibrium = zero force :0=f=ma=mdv/dt = m0 when velocity is constant dV/dt=0.
Does a change in force acting on an object change that object's acceleration?
F = ma (force equal mass times acceleration) Therefore a = F/m So acceleration changes in direct proportion to the change in force. Half the force gives half the acceleration.
How do you find acceleration given mass and distance?
Not enough information. One equation you can often use is Newton's Second Law: force = mass x acceleration Which, when solved for acceleration, gives you: acceleration = force / mass
A 3000 N force gives an object an acceleration of 15ms2. The mass of the object is?
Just use Newton's Second Law. That is, divide the force by the acceleration.
What force gives a mass an acceleration of 9.8 meters second?
Earth's gravity.

If the question gives you mass and Force and asks for acceleration what formula will you use?
A = f / m
A force of 1500 N gives a rocket an acceleration of 2.5ms2 what is the mass of the rocket?
it is 600kg
Force can also be referred to as the weight of an object?
Yes, the acceleration of gravity times the mass of the object gives a force that is the weight.
