The momentum of a moving object can be found by multiplying its mass by its velocity.
The formula for momentum (p) is: \[ p = m \cdot v \] where \( m \) is the mass and \( v \) is the velocity.
If the total net force on a system is zero and the mass remains constant, then the acceleration is zero.
According to Newton's first law of motion, if there is no net force acting on an object, it will either remain at rest or continue to move at a constant velocity, which means that its acceleration is zero.
Newton's second law of motion states that force equals mass times acceleration.
In mathematical terms, it is expressed as: \[ F = m \cdot a \] where \( F \) is the net force acting on an object, \( m \) is its mass, and \( a \) is the acceleration produced.
The scenario that describes an object experiencing zero net force is a balloon floating upward at a constant velocity.
In this case, the upward force (buoyancy) is balanced by the downward forces (gravity and drag), resulting in no net force acting on the balloon, which allows it to move at a constant velocity. For an object to have zero net force, it must be in a state of equilibrium, either at rest or moving with constant velocity.
