What is the definition for the term force?
The scientific definition of force is: the push or pull of an object.
What is the greater mass of an object is the force of lift?
If the mass of an object is greater than the force of lift, the object will not be able to overcome gravity and will not be able to lift off the ground. It is important for the force of lift to be greater than or equal to the mass of the object for it to be able to achieve lift.
What kind of force does a porter apply to lift an object?
A porter applies an upward force called the lifting force to lift an object. This force must be larger than the weight of the object to overcome gravity and lift it.
When using a lever to lift a 45 N rock a force in or a force out?
When using a lever to lift a 45 N rock, the force required would be an input force. This is because you are applying the force to the lever to lift the rock against the force of gravity. The output force would be the force exerted by the lever on the rock.
What is force of lift and thrust?
Lift is the force that acts upwards, perpendicular to the chord of the wing. Thrust is the force acting perpendicular to the propeller disc.
What force gets a plane into the air is?
the force is lift
What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
Is the definition of lever to make it easier for people to lift heavy objects or open things?
Both, and neither. Both, because levers successfully assist people in lifting heavy objects (which requires force) and opening things (which requires force). Neither, because the definition of a lever has nothing to do with how the theory is used.
Upward force on a bird's wing?
It is called Lift. The difference in pressure above and below the wigs as a bird moves through the air produces an upward force that causes the bird to rise.
What force present of you lift a pencil off the top of a desk?
The force required to lift a pencil off a desk is the gravitational force acting on the pencil. When you lift the pencil, you are exerting an upward force that overcomes the force of gravity pulling the pencil downward.
Whats the definition of load as it applies to levers?
The load in a lever system refers to the resistance or weight that the lever is meant to move or lift. It is the object or force that the lever is working against to perform its function.
Why are you doing work when you lift something but not when you carry it?
Its just due to the "physical" definition of work. In order for a force to do work on an object it must move (at least some component of it) parallel to the force. So when lifting, the force is up and the movement is up and the force does work. In carrying, the force is up but the movement is horizontal. They are perpendicular and the force does no work. False
