The forces acting on a flying ball are:
1. The frictional force exerted by air on the motion of the ball.
2. The gravitational force of the earth, of course.
Thrust, drag, lift and weight.
Yes. Gravity. Air resistance (friction again).
Gravity is working to pull the falling feather down to the ground.
Either an alarm clock or a Force (preferibly not the dark side, as that never turns out well).
no force act on it
the object will remain at rest until a force acts upon it.
An input force is what force you act upon a machine. The output is what it does for you in return.
Yes
[object Object]
Yes. Gravity. Air resistance (friction again).
Gravity is working to pull the falling feather down to the ground.
Yes. That's how the navigator of an airplane in flight is able to use a magnetic compass.
Forces of gravity ( gravitational force) pulls the meteor to earth
A unbalanced force must act upon it. ;)
Either an alarm clock or a Force (preferibly not the dark side, as that never turns out well).
LiftGravityThrustDragLift is the lifting force that allows airplanes to fly, gravity is the force pulling it back down.Thrust is the force that propels an airplane forward, drag is the aerodynamic friction slowing it down.These variables are constantly interacting with eachother, when an airplane is in straight and level flight, these forces are said to be in balance.
If the act together (in the same direction), the resultant force is the sum - 1300 gf (whatever that abbreviation means!). This is the maximum. If they act in opposite directions, the resultant force is the difference, 300 gf - and this is the minimum.
We have an important law in physics called: NET force = m * a m = mass a = acceleration A net force will produce an acceleration on an object, and that acceleration will change the object's velocity.
