The acceleration of an object varies directly as the force acting on it If a force of 240 newtons causes an acceleration of 150 ms². what force will cause an acceleration of 100 ms2?

240N causes= 150a
xN causes= 100a
X= 240*100\150
= 160N

What causes an object's velocity to change?
A change in velocity is caused by a change in acceleration. Objects do not speed up, slow down, or change direction unless they are pushed in some way. The acceleration (a) of an object with mass (m) produced by a given force (F) may be calculated using the equation a = F/m.
What does unbalanced mean?
Ubalanced force: is when two forces are acting on an object results in a net force and causes a change in the object's motion.
What causes motion?
If anything is acting on a partilce, it will keep moving along a straight line, with constant velocity (in all the inertial reference frames). In this sense, nothing causes the motion.A change in this kind of motion, that is, an acceleration or a curve in the trajectory, is caused by a force, according to the Newton equation F = dp/dt. "Nowadays" we prefer to avoid the concept of force F, using instead the idea of field, which is independet from the particle and from its parameters (mass, charge, ... ): you can say that the field permeate the space, whether the particle is there or not.
How do unbalanced forces affect motion?
-- An unbalanced group of forces on an object causes the object to accelerate in the direction of the net force. -- If an object is not moving, then the group of forces on it must be balanced, else it would be accelerated.
How does a centrifuge work?
Centripetal acceleration is the force inwards on an object moving in a circular motion.A centrifuge uses an acceleration (in terms of g, which is the acceleration due to gravity) that is specified by the user. A centrifuge uses 2 rotors at the same rotational speed but with different diameters to create 2 different accelerations.Particles of different masses will separate in the centrifuge because they move at different speeds due to acceleration.
What causes variation in velocity of particle?
Acceleration and so a force acting on the particle.
Do newtons make stuff move faster?
A newton is a unit of force, and a force (if unbalanced) causes an acceleration. Acceleration involves any change of velocity - not just making things faster.
What causes acceleration. two forces acting opposite each?
If there is acceleration, there must be an unbalanced force. That is, the vector sum of all the forces acting on the object is not zero. It may be a single force, or several forces that don't add up to zero.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
What do you measure force with?
Force is defined in physics as an influence that causes an object to change its rate or direction of movement or rotation. The relationship between force, mass and acceleration was defined by Isaac Newton in his second law of motion; if an object's mass and acceleration are known, it is possible to calculate the force. Here's how to measure force by measuring mass and acceleration.
What are newtons?
Newtons are a unit of force. A force of 1 Newton acting on a mass of 1 kilogram causes it to accelerate by 1 metre/second every second by Newton second law: force = mass x acceleration. A 1-kg mass that is dropped will accelerate down at 9.81 metres per second per second before it hits the floor, therefore the force acting it, which is its weight, is 9.81 Newtons. But the same 1-kg mass, on the Moon, accelerates one sixth as fast, and its weight is less, one sixth of the old weight, so its weight is only 1.63 Newtons.
How force is related to acceleration?
Force is equal to Mass times Acceleration. So if you are given an equation where you know two of the three variables you can find the third. You can also manipulate the equation as needed.
How does gravitational force affect acceleration?
The force of gravity causes objects to accelerate (speed up) when they fall. This is because of newtons law F=MA force equals mass times acceleration, meaning when you put a force such as gravity on a mass it will accelerate the mass
Is force acceleration?
No a force causes acceleration.
Why do things speed up or slow down?
Its all physics. Things speed up and slow down because of a force acting upon them. Newton's second law of motion states that the force applied to an object is equal to its mass times acceleration, i.e. F = MA. As a result force causes a change in acceleration, which causes a change in velocity. This can be positive or negative, depending on which direction the force is acting.
How its force related to acceleration?
Force causes acceleration.
How does the mass vary with acceleration of constant force?
In theory, if you keep the force constant and vary the acceleration, the mass will vary inversely to the acceleration. In other words, if the acceleration increases, the mass will decrease; if the acceleration decreases the mass will increase. This is according to Newton's 2nd Law illustrated by the equation a=F/m. This is really a mental exercise, because this particular experiment could not actually be performed in a typical physics laboratory.
