I Need to know what happens when a pram is moving i need to 1Know when pram is speeding up and slowing down and what forces affect wheels 2When pram is speeding up normal slowing down?
The main forces acting on the pram will be the force the person pushing the pram exerts on it, the friction against the ground and air resistance. When the pram is speeding up the force the pusher exerts will be larger than the combined force of the air resistance and the friction against the ground. When the pram is moving at a constant speed the forces acting on it will be balanced I.e. pushing force= air resistance+friction. When the pram is slowing down the air resistance and the friction will be greater than the pushing force.
Which force makes a feather fall to the ground more slowly than a stone?
The feather falls slower because it has air restistance. The air pushes up on it. The rock falls faster because it's mass and how it doesn't have air resistance. Also, because toilet seats produce a gas, reacting with the feathers on a feather, making the feather rise.
Which fluid force opposes lift?
Answer The essence of your question is very complicated and concerns fluid mechanics but I will simplify it as much as possible. In short, the force that opposes lift is weight (the gravitational force acting on an object's mass). If lift is greater than weight leaving all other variables such as air resistance are left the same the object is ascend. If weight is greater than lift the object will descend if already in the air or never take off if still on the ground. This question is at the heart of why planes fly. The leading edge of the wing causes the air on top to travel than the air on the bottom. Bernoulli's principle says as the speed of a fluid increases the pressure of the fluid decreases. As a result, the air on top of the wing has a lower pressure than the air on the bottom. Fluid go from high to low pressure. The air on the bottom of the wing exerts a force upward and thus the plane rises. It is important to know the other two force crucial in the flying of plane. They are thrust and drag. Thrust is the reactionary force to the force that push air out of a jet engine or from propellers. Drag is the force of air resistance and it is proportional to the velocity of the object. In other words, as the object goes faster the force trying to slow it down increases as well. This continues until the object reaches terminal velocity. Terminal velocity is the point at which the force acting on an object and the frictional force become equal in magnitude and opposite in direction. As a result, the net force acting on the object is zero and the object stops accelerating and falls at a constant rate from that point on.
If you use the same force on a less massive object what happens to the acceleration?
Force equals mass times acceleration, so an alternative formula is acceleration equals force divided by mass. Therefore if the mass is decreased, the acceleration goes up. Thus a 100 HP engine on a motor cycle produces more acceleration than the same engine on a car.
Is 2.5mm bigger than 2mm?
2 is smaller than 3, so 2mm is smaller than 3mm.
Which encounters the greater force of air resistance a falling elephant or a falling feather?
A falling elephant encounters a greater force of air resistance than a falling feather does. The force of air resistance can't be greater than the weight of the falling object. When the force of air resistance is equal to the weight of the falling object, the object stops accelerating, its falling speed becomes constant, and the force of air resistance doesn't get any bigger. So the force of air resistance against a falling feather can't be greater than the weight of the feather. But the force of air resistance against a falling elephant can be, and undoubtedly is, greater than the weight of a feather.
Is the force which prevents the wagon from moving greater than equal to or less than the pull of the engine?
Air friction and rolling resistance
A feather is in freefall when the force of gravity is greater than the force of air resistance is equal to the force of air resistance is less than the force of air resistance is the only force acting?
"Free fall" means that gravity is the only force acting on a body.
Why is gravity a bigger force than air resistance?
It isn't, necessarily. But the force of gravity is constant, whereas the force of air resistance depends on how fast you're moving through the air. So when you begin to fall, gravity is stronger, and it makes you fall faster and faster. But as your speed increases, so does the force of air resistance, and eventually, the force of air resistance builds up to be equal to the force of gravity. At that point, you keeep falling, but your speed doesn't grow any more.
What happens when the resistance force is larger than the effort force?
no movement
What happens scietifically when 1000 of force to an object with 1100N of resistance force?
What happens is that the resistance of 1100 newton is the MAXIMUM resistance. If a force of 1000 newton is applied, the actual resistance will also be 1000 newton. If a force greater than the maximum force of friction is applied, the object will start to move.
What does effort forces mean?
The effort force is the force that is applied to an object that causes it to move. The object reciprocates with a resistance force. If the effort force is greater than the resistance force, the object moves.
Why does a motor have a bigger resistance than a bulb?
There is no particular reason why a motor should have a bigger resistance than a bulb. A motor's resistance must depend on what current it draws at the particular voltage it was designed to run on. Equally, a bulb's resistance must depend on what current it draws at the particular voltage it was designed to run on. A particular motor may have a higher resistance than one kind of bulb but that same motor may have a lower resistance than another kind of bulb.
What happens to a box when the pushing force is is bigger than the friction force?
Nothing
Is there an engine bigger than the VW V12?
There are many.
How big is the US air force?
Bigger than a plane
Does air resistance resist motion?
Yes air resistance does resist motion of an object. If the object is very small or moving only slowly air resistance will be low. But the faster the object travels the greater will be the resistance. In fact, the reason a car doesn't go faster than it does is due to the air resistance, which will require more power to overcome than the engine can deliver.
