The resistance force when unscrewing a jar comes from the friction between the lid and the jar. This frictional force can vary based on factors such as the tightness of the lid, the presence of any sticky substances, and the material of the lid and jar. Applying force in the opposite direction overcomes this resistance force to open the jar.

What examples best describes using an inclined plane Rolling a wheel up a hill Riding a bike on a flat path unscrewing a lid from a jar taking a trunk down from a shelf?
Rolling a wheel up a hill and riding a bike on a flat path are the examples that best describe using an inclined plane because they both involve overcoming gravity and requiring less force than lifting vertically. Unscrewing a lid from a jar and taking a trunk down from a shelf are not examples of using an inclined plane.
Which force on an airplane can also be called a resistance force?
Gravity is the main resistance force on any aircraft. Wind resistance would be second.
How are effort force and resistance force different?
Effort force is the force applied to overcome resistance force in order to move an object, while resistance force is the force that opposes the motion of an object. Effort force acts in the direction of motion, whereas resistance force acts in the opposite direction. The ratio of effort force to resistance force is a measure of mechanical advantage in simple machines.
What is the meaning of resistance force?
Resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pound-force. Resistance force is used to calculate the work output using the equation: Work output = Resistance force * resistance distance
What is the ration to resistance force to effort force?
The mechanical advantage is given by the ratio of resistance force to effort force. It represents the factor by which a simple machine multiplies the force applied to it. Mathematically, it can be calculated as mechanical advantage = resistance force / effort force.

Is air resistance a pull force or push force?
Yes resistance would be a push force.

What is the formula to find resistance force?
The formula to find resistance force is given by R = F/A, where R is the resistance force, F is the force applied, and A is the area over which the force is applied. This formula is often used in physics and engineering to determine the resistance force in various scenarios.
What is the ratio of resistance force effort force?
The ratio of resistance force to effort force is equal to the mechanical advantage of a simple machine. This ratio indicates how much the machine amplifies the input force to overcome resistance. It is calculated as the ratio of the distances from the fulcrum to the points where the effort force and resistance force are applied.
What force overcomes resistance?
The force that overcomes resistance is typically referred to as the "net force." Net force is the vector sum of all forces acting on an object and determines how the object accelerates. When the net force is greater than the resistance force, the object will overcome the resistance and accelerate in the direction of the net force.
How does a water balloon get suction into a jar?
When a water balloon placed over the mouth of a jar is squeezed, the air inside the jar is compressed. When this compression occurs, the pressure inside the jar drops slightly, creating a suction force. This suction force, produced as a result of the pressure difference between the outside and inside of the jar, causes the water from the balloon to be drawn into the jar.
Why is resistance force called resistance force?
because it is resistant to the led lights and Mercury
What is the resistance are of a lever?
The resistance arm of a lever is the distance between the fulcrum (pivot point) and the point where the resistance force is applied. It determines the amount of force required to move the resistance, with a longer resistance arm requiring less force to overcome a given resistance.
