Circular Motion
Speed of a car remains constant during circular motion, but this value changes because it is the vector form of the speed in uniform circular motion.
what is velocity?
When the radius between two planetary objects is doubled, this happens to the force.
what is divided by four?
the gravitational field strength on the surface of the earth is also known as this.
what is the acceleration due to gravity OR 9.8 m/s2?
Electrostatic force is described in this way rather than in terms of positive and negative.
what is attractive or repulsive?
Like electrostatic force, electric fields can be attractive or repulsive. However, this kind of force is always attractive.
what is gravitational force?
When moving in a vertical circle, the tension in the rope is greatest here.
what is the bottom of the circle?
Kepler's first law states that objects in orbit move in this pattern.
what is elliptical?
Planet A is twice as massive as Planet B but Planet B has twice the radius of Planet A. This planet has the greater gravitational field.
what is Planet A?
If the radius between two particles is cut in half, the force will increase by this factor.
what is 4?
When solving electrostatic force or electric field problems, we also use the absolute value of this value/variable and then label the force or field as attractive or positive.
what is q OR charge?
When determining the minimum velocity necessary to keep an object moving in it's circular path, we use this equation.
what is Vmin = the square root of (g * r)?
The mass of the Earth is 5.97×1024 kg, and the mass of the Moon is 7.35×1022 kg. The average distance between the centers of the Earth and the Moon is 3.84×108 m. This is the gravitational force between the two planetary objects.
what is 1.98 * 1020 N?
A gravitational field is observed on an object at a distance of 12.0 m and it has a mass of 5000 kg. This is the magnitude of the field.
what is 4.81 * 10-5 m/s2?
The electrostatic force between two particles is 4.0 * 10-3. If the charge of one of the particles is doubled and the radius is also doubled, this is the new electrostatic force.
what is 2 * 10-3 N?
A electric field has a magnitude of 12 N/C from this distance away from a point charge of q = 2.5 * 10-6 C.
What is 43. 3 m?
A car is moving in a circular path with a radius of 50.0 m at a constant speed of 20.0 m/s. If the centripetal force acting on the car is 3,200 N, this is the mass of the car.
what is 400 kg?
what is 165 years?
a field is also known as this.
what is an area of influence?
If the electrostatic force between two particles is 3.2 * 10-2 N and the charges of both particles is 1.6 * 10-19, this is the distance between the two particles.
what is 8.48 * 10-14 m?
An electric field exists with this magnitude at a distance r = 60 m from a point charge q = 2.0 * 10-6 C.
what is 5 N/C?
This is the net force keeping an object in circular motion.
what is centripetal force?
A satellite is orbiting the Earth at an altitude of 5.0×105 m (500 km) above the Earth's surface. The mass of the Earth is 5.97×1024 kg, and the radius of the Earth is 6.371×106 m. This is the orbital velocity of the satellite?
what is 7,612.72 m/s?
If the gravitational field on the surface of the earth is 9.8 m/s2, and the mass is 5.97 * 1024, what is the radius of earth?
what is 6.36 * 106 m?
Two small charged particles are placed in space, separated by a distance of 0.05 m. Particle A has a charge of +2.0 μC (microcoulombs = 10-6 C), and Particle B has a charge of −3.0 μC. This is the electrostatic force between them.
what is 21.6 N?
A point charge q =+ 4.0 μC creates an electric field with a strength of 1.8×105 N/C. If the distance is changed so that it is 3/4 of the original distance, the magnitude of the field will be this.
what is 320,000 OR 3.2 * 105 N/C?
