the acceleration decreases
The acceleration of the swing would increase if one person pushed two people on it because the combined mass of the two people would be greater than just one person, requiring more force to achieve the same acceleration. Increased force would result in greater acceleration.
The acceleration of an object can be increased by either increasing the force acting on the object or by decreasing the mass of the object.
The force equal mass times acceleration, if force remains the same, and mass is doubled, then acceleration must be cut in half.
it gets decreased
From the equation F=ma, fixing F (force) as a constant, changing m(mass) effects directly to a(acceleration). Increasing mass, acceleration drops, decreasing mass, acceleration increases. Acceleration= change in velocity/ time.
By F = ma, if the force remains constant, and the mass decreases, this would mean that the acceleration has increased by exactly the same factor as the decrease in mass. That is, if the mass of a substance was halved, its acceleration would have doubled exactly.
Since Force = Mass x Acceleration If force is held constant and one varies the mass then the acceleration will vary according to the equation: Acceleration = Force / Mass As a result, the acceleration is inversely proportional to the mass of the object. In other words, if one increases the mass of the object, the acceleration of the object will decrease proportionally. Similarly, if one decreases the mass of the object, the acceleration will increase proportionally.
If Earth's mass increased, then the gravitational force between Earth and the moon would also increase. The moon would be more strongly attracted to Earth. The acceleration between the 2 would increase also.
If the mass is increased and gravity remains constant, the acceleration will decrease. This is because the force acting on the object remains the same due to gravity, but as the mass increases, the object will experience a greater resistance to acceleration.
It would slow the object down because it now weighs more.
What you are wanting to know is found in Newton's Second Law. The equation used is Acceleration = (Net force)/(Mass) or Force equals mass times acceleration; [F = m * a] So, if the mass is increased but the force remains constant, then the acceleration will decrease. (For the same force applied, larger masses experience less acceleration than smaller masses.)
If the angle of a mass is increased, the horizontal acceleration would decrease due to the component of gravitational force acting perpendicular to the direction of motion increasing. This component would counteract some of the horizontal acceleration.
