We've spent the last 500 years trying to get used to the idea that no force is required
in order for an object to move. Force is required only to change the speed or direction
of an object's motion, but the object keeps moving just fine at a constant speed and in
a straight line, forever, with no forces on it.
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.
Yes, an object at rest can have forces acting on it. The vertical forces acting on an object at rest would include gravity pulling it downward and the normal force from a surface pushing it upward to balance the force of gravity.
The net force acting on an object is the combination of all individual forces acting on it. It is the vector sum of all forces, taking into account their magnitudes and directions. The net force determines the acceleration of the object according to Newton's second law of motion.
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
If an object is immobile, it means that the net force acting on it is zero. This is in accordance with Newton's First Law of Motion which states that an object at rest will remain at rest unless acted upon by an unbalanced force.
In principle, any force acting on an object is unbalanced, UNLESS there is a second force in the opposite direction, acting on the same object.
The total force acting on an object is called the net force. It is the vector sum of all the forces acting on the object. The net force determines the object's acceleration according to Newton's second law of motion.
If the normal force and gravitational force acting on an object were unequal, the object would either accelerate or decelerate in the direction of the net force. If the normal force is greater, the object will move upwards; if the gravitational force is greater, the object will move downwards.
An unbalanced force acting on an object is a force that causes the object to accelerate or change its direction. When the net force acting on an object is not zero, it will result in the object experiencing motion. This can lead to the object speeding up, slowing down, or changing its path of motion.
that is called the net force; it is a vector sum of all the forces acting on it
Doubling the force acting on a moving object would cause the object to accelerate at a faster rate, leading to an increase in its speed. This is in accordance with Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force acting on it.
That would be the net force acting on the object.
An object in equilibrium is not moving, as all the forces acting on the object are balanced. If the object were to be in motion, it would no longer be in equilibrium as there would be an unbalanced force acting on it.
There would have to be an unbalanced force put an object in motion but once in motion no force is necessary for it to remain in motion
0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero. Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.
True. The buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid that the object displaces. Therefore, by knowing the weight of the object, you can determine the buoyant force on it.
Yes, an object at rest can have forces acting on it. The vertical forces acting on an object at rest would include gravity pulling it downward and the normal force from a surface pushing it upward to balance the force of gravity.
