To keep a sled accelerating downhill what must the force of gravity be greater than?
The force of gravity must be greater than the normal force.
To keep a sled accelerating downhill the force of gravity must be greater than the normal force?
"friction"
What force starts a marble accelerating down a hill?
If nobody pushed it, then it had to be either gravity or the wind.
What is volicity?
Terminal velocity- When a falling object is no longer accelerating; the force due to gravity is equal to the opposing force of air resistance.
Is it true that a sled accelerating downhill the force of gravity must be greater than the normal force?
Not at all. The force of gravity must be greater than the friction force, but if the sled is on any kind of slope, then it doesn't matter what the normal force is.
What is terminal volicity?
Terminal velocity- When a falling object is no longer accelerating; the force due to gravity is equal to the opposing force of air resistance.
What is an accelerating force?
An accelerating force is the force which causes accelerated motion.
What would you call it when air resistance the force of gravity and a falling object stops accelerating?
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
What is a car's g-force?
There are accelerating G's, Braking G's and cornering G's. It is the force in that direction the car and occupants are exposed to. 1 G is the for of gravity.
Why do you feel heavier going up a lift?
The force of the lift accelerating you upward is added to the force dur to gravity. You feel this as added weight. The same effect happens when it stops moving going downward, and the opposite occurs when you begin going down or stop going up. You are not resisting the force of gravity and you do not feel the weight; for some of that time, you are actually freefall.
If you skateboard down and steep hill and back up In which location are you accelerating?
down the hill. the force of gravity pulls you down.
When you stop pushing on a box and it slows down is it balanced or unbalanced force?
Unbalanced , because as long as it is moving it is accelerating therefor it is unbalanced . Now if it is at a complete rest then it is not accelerating therefor it would be a balanced force .
