With regard to Newton's First Law only, about all you could say is that if an object
has no centripetal force acting on it, then it continues in constant, uniform motion.

∙ 11y agoForce = mass x acceleration. Acceleration = force / mass.
A force is needed to produce an acceleration (change of velocity). An object moving in a circle changes its direction, therefore its velocity changes; this requires a force, equal to mass x acceleration. (The centripetal acceleration can be calculated as a = v2 / r - speed squared divided by the radius of curvature.)

How does speed affect centripetal force?
Force (newtons) = mass (kg) * acceleration ((m/s)/s) but > acceleration in a circle = velocity 2 / radius So > (centripetal) force = mass * (velocity 2 / radius)
What is the relationship between radial force and angular velocity squared?
By radial force, we can assume you mean centripetal force Centripetal force = (Mass)(Radius)(Angular velocity)2
If the radius of rotation and the mass being kept constant how does the centripetal force vary with the speed of rotation of the body?
Recall centripetal force = m v^2 / rAs m and r are found to be constants then centripetal force F is directly proportional to the square of the velocity of the body
What is the centripetal force that follows a car to move around a sharp curve in a roadway?
The centripetal force (f) can be calculated from:.f = m * (v^2 / r ) , where..m = mass of car (say 1 000 kg)v = velocity (say 30 metres / second)r = curve radius to centre of gravity of car ( say 50 metres)so:f = 1000 * (900 / 50) = 18 000 newtons
When an object experiences centripetal accelerationin which direction does it accelerate?
Its changing direction ;)

What is A 0.25 kg stone tied to a 0.5 m string whirls at a speed of 4 m s What is the centripetal acceleration acting on the stone?
Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2The centripetal acceleration doesn't depend on the stone's mass.(The centripetal force does.)The centripetal acceleration doesn't "act on" the stone.(The centripetal force does.)The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.
Does gravity zero at equator according to centripetal force explain?
gravity provides pretty much the same force on a given mass anywhere on earths surface, due to its mass only and irrespective of earth spin. example: say your 70 kg mass at equator (where centripal action is greatest) force due to gravity : f = (G*m1*m2)/d^2 = 687.4 newtons force due to centripetal action at equator : f = mass * (v^2/r)= 70*0.034 = 2.38 newtons
What is the relationship between radial force and angular velocity squared?
By radial force, we can assume you mean centripetal force Centripetal force = (Mass)(Radius)(Angular velocity)2
What happens to the size of the centripetal force due to gravity acting on the satellite if the satellite moves farther from earth?
The centripetal force decreases. F= mv^2/r = mGM/r^2
If the radius of rotation and the mass being kept constant how does the centripetal force vary with the speed of rotation of the body?
Recall centripetal force = m v^2 / rAs m and r are found to be constants then centripetal force F is directly proportional to the square of the velocity of the body

Why an astronot in orbiting satellite has a feeling of weightlessness?
the net force on bodies in stable orbit is nil, the force of gravitational attraction , is balanced by the centripetal force of velocity in a circle. . example, any orbit radius ( if orbit time not important) choose your orbit radius, calculate force of gravity, tailor velocity to produce balancing centripital force . f=((G*m1*m2)/d^2) force of gravity f = m2 *( v^2/d ) centripetal force G = newtons constant m1 = earth mass m2 = satellite mass d = orbital distance
A car with a mass of 1200 kilograms is moving around a circular curve at a uniform velocity of 20 meters per second The centripetal force on the car is 6000 newtons What is the radius of the curve?
80 meters. Since the only force on the car is centripetal force then:Fc = macac = v2/rFc = (mv2)/rSolve for rr = (mv2)/Fcr = (1200)(20)2/(6000)r = 80m(See my work in the link below.)
Is Work done by centripetal force is zero?
An object moves in a circle at constant speed. The work done by the centripetal force is zero because: 1. the displacement for each revolution is zero 2. the average force for each revolution is zero 3. there is no friction 4. the magnitude of the acceleration is zero 5. the centripetal force is perpendicular to the velocity

What is the formula in getting centripetal force and it's net horizontal force?
One formula for centripetal force is v2/2 - the square of the velocity (speed, actually) divided by the radius. Another is omega2r, where omega is the angular speed, in radians/second.One formula for centripetal force is v2/2 - the square of the velocity (speed, actually) divided by the radius.
