Source sentences:
text: If the mass of the object is constant, this law implies that the acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object.
text: The force acting on an object is equal to the mass of the object multiplied by its acceleration (rate of change of velocity).
text: The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time.
text: Summary To draw a free-body diagram, we draw the object of interest, draw all forces acting on that object, and resolve all force vectors into x– and y-components.
text: For example, an object suspended on a vertical spring scale experiences the force of gravity acting on the object balanced by a force applied by the "spring reaction force", which equals the object's weight.
text: For an object accelerating in circular motion, the unbalanced force acting on the object equals:
text: To find the force of buoyancy acting on the object when in air, using this particular information, this formula applies:
text: The net force acting on the object is equal to zero.
text: When a net external force acts on an object, how does its acceleration depend on the force acting on the object and the mass of the object?
text: In cases where an object is not weightless, as in the above examples, a force acts non-uniformly on the object in question.
text: The normal force is one of the several forces which act on the object.
text: Calculate the other forces present Calculate the other forces that are acting on the object.
text: At first, you may want to draw a circle around the object of interest to be sure you focus on labeling the forces acting on the object.
text: Include all forces that act on the object, representing these forces as vectors.
text: The force (F) acting on the object is demonstrated in Newton’s second law, which states F = ma, so the force = mass × acceleration.
text: When an object is free falling, this means the only force that is acting on the object is gravity.
text: In the cases discussed above, we observed that force acts on an object only when the force is in contact with the object.
text: When the forces acting on an object are balanced, they cancel each other out.
text: When the forces acting on an object do not cancel out each other, a net force acts on the object.
text: Work is defined as force acting on an object in the direction of motion.
text: Note that the net force is the sum of all the forces acting on an object.
text: However, some forces can act on objects without physical contact.
text: For instance, the gravitational force acting upon an object can be seen as the action of the gravitational field that is present at the object's location.
text: As mentioned above, the force of gravity acting upon an object is sometimes referred to as the weight of the object.
text: The Free-Body Diagram Interactive allows a learner to practice identifying the forces that act upon an object and to express such an understanding by the construction of a free-body diagram.
