What is the difference between a stationary and a resultant force?
Does a stationary object remain stationary if there is no resultant force?
What happens if a force acts on a stationary object?
What is the resultant force on a car?
What is a resultant force?
Why does a stationary object stay stationary if it is moving?
resultant force. acts on it. If the resultant force on an object is zero, this means: a stationary object stays stationary. a moving object continues to move at the same....

A resultant force is the overall force that acts on the object. Remember that forces are vectors. When you calculate the resultant force you need to also say the direction it is...
Newton's First Law of motion states that when there's no resultant force, a stationary object stays stationary, it doesn't start moving, and a moving object keeps moving at the same speed, in the same direction. A resultant force causes acceleration and that can produce a change in velocity, which could be a change in speed, direction, or both.

Let's start with the simple case in which an object is subject to two forces that act in the same direction: The resultant force is in the same direction as the two forces, and has the magnitude equal to the sum of the two magnitudes:
Let's consider the case in which an object is subject to two forces that act in opposite directions. If the two forces are equalin magnitude: The resultant force will be zero because two opposite forces cancel each other out. On the other hand, if the two forces are not equalin magnitude: The resultant force will be in the same direction as the for...
Let's now consider the case in which an object is subject to more than two parallel forces: To find the resultant force in this case, we first sum all the forces that go in one direction, and then all the forces that go in the other direction: At this point, we have two forces that are in opposite directions, which is a case that we already know ho...
In the previous cases, we have forces that are all parallel to one another. It's time to consider the case in which an object is subject to two forces that are not parallel. For example, let's assume that we have a block subject to two forces, F1 and F2. F1 has magnitude 50 N and is applied at a 45° angle, whereas F2 has magnitude 60 Nand is applie...
Finally, let's examine the case in which an object is subject to more than two non-parallel forces. For example, suppose we have an object that is subject to three forces, F1, F2, and F3. The magnitude of each force is shown below: The free-body diagram of the object looks like this: We can find the resultant force Rusing the same process that we u...
A resultant force is a single force that describes all of the forces operating on a body. When many forces are applied to an object they can be combined (added) to produce one final force which describes the combined action of all of the forces. This single resultant force determines:
Stationary - a stationary object is not moving. Resultant force - A resultant forces the sum of all forces acting on an object. Frictional force - Frictional forces act between surfaces, to oppose the movement of an object. Gravitational force - The gravitational force on an object pulls it downwards, towards the Earth.
A stationary object remains stationary if there is no resultant force. Every action has an equal and opposite reaction. Correct answer: A moving object’s velocity stays the same if no resultant force acts.
