Newton's first law, which states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
Unbalanced
Unbalanced force=mass of object x acceleration of object
A hill is not a force, balanced or otherwise. According to Newton's Second Law, if there is any unbalanced force on an object, the object accelerates - its velocity changes.
If the parachutist is just falling down vertically, he is falling because of the unbalance force. Gravity is pulling him down. Gravity is stronger than the air resistance that is "keeping him up". The two unbalanced forces: gravity & air resistance. Because they are imbalance, he is accelerating towards the Earth's surface at 9.8 meters per second.
Newton's Second Law. Net force = mass x acceleration.
It can accelerate or decelerate, depending on the direction of force
If the vector sum of forces on an object is zero, the forces are said to be balanced. Otherwise they are said to be unbalanced. Unbalanced forces will cause an acceleration, according to Newton's Second Law (a = F/m, where F is the net force, that is, the vector sum of all forces acting on the object).
When two or more forces act on an object, if the sum (vector sum) of the forces is zero, the forces are said to be balanced. Otherwise the forces are unbalanced. According to Newton's Second Law, an unbalanced force will cause an acceleration.
During the time, you're pushing it, the forces are unbalanced. Once you stop, they are balanced. Unbalanced forces result in a change in motion. Balanced forces produce no change.It's kind of funny that you're pushing your box 1800 miles per hour, though! :)
as stated in newtons second law of motion- an object acted upon by an unbalanced force will accelerate in the direction of that force
The result of an unbalanced force is an acceleration. Newton's Second Law (as it is usually stated nowadays) gives the relationship; it states that: F = ma (net force = mass x acceleration)
2 Forces are unbalanced when an object that is not moving starts moving or changes speed or direction. Balanced forces are the opposite they are where an object that is not moving stays still or an object that is moving stays at a constant pace.
Unbalanced force=mass of object x acceleration of object
as stated in newtons second law of motion- an object acted upon by an unbalanced force will accelerate in the direction of that force
Doesn't matter Balanced Force would mean the object is traveling at a constant velocity due to Newton's First Law of Motion (Law of Inertia) Unbalenced Force would mean the object is accelerating (or decellerating) due to Newton's Second Law of Motion
