Why do two masses have the same acceleration?
I said the two masses have the same acceleration because the tension throughout the string is equal. The combined mass pulls each other at the same rate becauseb oth have the same foreces acting upon them. That is correct.
What is the relationship between acceleration and mass?
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
What happens to acceleration when you double the mass?
The math behind this is quite simple. If you double the force, you double the acceleration, but if you double the mass, you cut the acceleration in half.
How do you find the acceleration of a system?
Newton’s second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. In equation form, Newton’s second law of motion is a=Fnetm a = F net m .
How do you find the force of two masses?
Application of Newton’s second law to two masses. a = m/s² Then the force exerted on mass m2 can be determined.
Why is the acceleration of a system the same?
Now, since the displacements of the two objects (in their respective directions) must be the same in any given time interval, the velocities must be the same (just divide by a short time interval and take it to zero). Likewise, the accelerations must be the same as well since the velocities are the same.
Do all objects in a system have the same acceleration?
The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration.
Which of the following describes the relationship between mass and acceleration according to Newton’s second law?
Summary. Newton’s second law of motion states that the acceleration of an object equals the net force acting on the object divided by the object’s mass. According to the second law, there is a direct relationship between force and acceleration and an inverse relationship between mass and acceleration.
Does mass affect acceleration?
Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass.
What happens when mass doubles?
The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.
What happens to force when you double the mass of the object?
If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.
