What force slows things down?
Friction, when moving sideways. Upthrust when you are trying to go down. gravity when you are trying to go up
What happens to force when mass increases?
Say someone weighing 50 lbs sits down on a chair. Gravity pushes down on the person while the chair pushes upwards with enough force to keep the person up. Gravity pushes down with the same force all the time, it doesn't change.
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.
In what direction does the force of air resistance act?
As far as I understand the direction of the force of air resistance acts in the opposite way to which you are going... In other words if a ball was thrown up at 20 m/s and the force of air resistance was 1m/s2 then for every second the ball goes up, it would slow down by 1m/s (assuming there was no gravity). The same applies if it was going down at 20 m/s it would slow down by 1m/s. When a parachutist opens a parachute, gravity tries to pull it down and air resistance keep it up.I think so.
What force is acting when you are sitting on a chair?
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
Is a force that pushes down?
Gravity
How floatation works?
floataiton is really just bouyancy. the gravity pushes down and the buoyancy pushes up! at least i think it works that way.
Why flames of a fire rise even though gravity pull thing downwards?
Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.
Dropping a paracute does not change what?
because air resistance pushes up on it and gravity pulls it down and together they work to slow it down.
What role does gravity play in air density?
it pushes things down
Are there forces acting on a car at rest?
Yes. Gravity pulls it down; the road, or any surface the car is resting on, pushes it up.
Is the tides caused by the moon?
Yes, The moon's gravity pulls the water up and pushes it back down, making what we know as Tides.Yes
Do helicopters defy gravity?
The rotor blades are designed so that as they spin they push down on the air, which in turn pushes up on the blades, creating lift that acts counter to gravity.
Why are you lighter in water than on land?
You are not really lighter, in the sense that gravity still pulls you down. But on the other hand, the water pushes you up.
Which force pulls everything down to earth?
The force that pushes downward on objects on earth is called gravity.
What are the reasons for polarity?
the ways when gravity pushes down on a liquid but can still keep it together
Why does a ship not sink?
ships do not sink because gravity pushes it up
