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.
What is the upward force of air against a moving object?
= the (square of the velocity (m/s) * drag coefficient ) newtons if terminal velocity is known (forces balanced , no further acceleration), drag coefficient can be found. say terminal velocity(tv) = 70 m/s, acceleration due to gravity(g) = 9.8 m/s^2, mass(m) = 80kg m * g (force down) = tv^2 * drag coefficient (force up) at terminal velocity then m * g / tv^2 = drag coefficient 80 * 9.8/4 900 = 0.16
Does tension change in a parachute?
Yes: The force acting down is constant (mass * g) The force acting up = velocity 2 * drag coefficient At chute opening, the velocity is at its maximum, so up force due to drag is at its maximum. (maximum tension) Drag force reducing with diminishing velocity, to landing terminal velocity (minimum tension)
Why does a parachutist have two terminal velocities?
Because the drag coefficient increases when the chute opens..Force down (newtons) = mass (m) * acceleration due to gravity (g)Force up (newtons) = velocity2 * drag coefficient.Terminal velocity is where up and down forces balance.Say mass (m) = 100 kg, g = 9.82, then force down = m * g = 982 newtons, say terminal velocity (v) prior to chute opening = 70 m / s, then force down = force up so 982 = v2 * drag coefficient, so drag coefficient = 982 / 4900 = 0.2without chute.Terminal velocity with chute open, say 8 metres / sec, so drag coefficient= 982 / 64 = 15.34 with chute open.
This is exerted on a jack handle to lift a car?
G force
Does burnout paradise support a racing wheel?
Yes. it supports Logitech force gt Logitech g 25 and g 27. u dont have any tell me
How Fast does a bike roll down a hill?
It depends on how you push it down. Terminal velocity (top speed) is when the driving force is matched by the two opposing drag forces, air drag force and rolling resistance force. The (constant) driving force (due to gravity) you get from : force (N) = mass (m) of bike and rider in kg * g * sine ( incline angle in degrees) ) ( g = local gravity rate (use 9.8 (m/s)/s ) ) The air drag force in newtons = drag coefficient (use 0.24) * velocity ^2 (velocity is in m/s) The (constant) rolling resistance force in newtons = m * g * cosine (incline angle ) * rolling resistance coefficient (use 0.03). Sequence : guess at top speed (in m/s), calculate the for and against forces for that speed, and adjust this guess until its zero.
Why do you fall back when a car speeds up?
Because of g force and gravity
How much g force cornering in a car?

What is the relation between weight of the body and speed of the air?
terminal velocity is forces balanced force down = mass * g (newtons) force up = v^2 * drag coefficient (newtons) m*g = v^2*dc dc=(m*g)/v^2
What is the electronic display on a Renault Clio sport O2 model counting when it has the picture of a car with a G above it?
G force
What is the highest g-force ever endured?
Formula One racing car driver David Purley survived an estimated 179.8 g in 1977 when he decelerated from 173 km·h−1 (108 mph) to 0 in a distance of 66 cm (26 inches) after his throttle got stuck wide open and he hit a wall.
