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 is the acceleration of a 20-kg block if the net force acting on it is 100 N?
According to Newton's Second Law, F=ma, just divide the force by the mass. Since you are using SI units, the result will be in m/(sec square).
What is the effect of acceleration on an object which is not moving?
An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.
When earth angular velocity increase then gravitational acceleration increase?
Let's be very accurate when describing accelerations in this question. Consider a person at the equator. The gravitational force of attraction on him is constant whether or not the earth is rotating. This acceleration is called the acceleration due to gravity (ag) Now, since the earth is rotating about its axis, there has to be a centripetal force on the person. It is the gravitational force which provides the centripetal force. Thus, there is a centripetal acceleration on the person (ac) Finally, the rest of the gravitational force causes the person to accelerate towards earth. This is called the acceleration of free fall (af) This gives ag = ac + af ac is given by the equation: ac = w2r where w is the angular velocity and r is the radius of rotation If the angular velocity of the earth increases, centripetal acceleration will increase. af = ag - w2r Therefore, the acceleration of free fall will decrease.
Acceleleration is directly proportional to force but inversely proportional to mass what does this mean?
It means that if you increase the force, acceleration will increase. However, if you increase the mass of the object you are accelerating, the acceleration will decrease. It all stems from the basic equation F=ma, where F is the force, m is the mass and a is the acceleration. Rearranging for a gives a=F/m. This means that as m is the denominator, if it doubles and F remains constant, a will halve.
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 is newtons second law of motion formula?
The original formula Force=(mv-mu)/twhere m-mass, v- final velocity, u- initial velocity, t- timeThe derived form Force= mass x acceleration
What is the definition of formula?
It's an equation that gives a useful answer.y = x2 + 4 is an equation, but the answer depends on the value of x, and has no units.f = ma (force = mass times acceleration) will give you the numerical value of force f needed to accelerate any object of mass m, at an acceleration value of a. This is a formula.Many people confuse the two:Useful answer with actual dimensional values?Formula.
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 force gives a mass an acceleration of 9.8 meters second?
Earth's gravity.
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) ].
A force of 1500 N gives a rocket an acceleration of 2.5ms2 what is the mass of the rocket?
it is 600kg
What is formula for aceleration?
There are, of course, several formulae that involve acceleration. The basic definition of acceleration is: acceleration = delta velocity / delta time, that is, to get average acceleration, divide the difference of velocity by the time that passed. The same formula also gives you the instant acceleration, if the acceleration is constant. If you want to get instantaneous acceleration, and the acceleration changes, then you need calculus: acceleration = dv / dt (that is, take the derivative of the velocity).
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.
