What are the formulas for that force?
What is the source of the force that maintains the circular motion in the following:
a bicycle moving around a flat circular track.
the bicyclist moving on the bike around a flat circular track.
a bicycle moving around a curved circular track.
A girl sits in a tire that is attached to an overhanging tree limb by a rop 2.10 m in length. The girl’s father pushes her with a tangential speed of 2.50 m/s. If the magnitude of the force that maintains her circular motion is 88.0 N, what is the girl’s mass?
A 905 kg test car travels around a 3.25
km circular track. If the magnitude of the force that maintains the
car’s circular motion is 2140 N, what is the car’s tangential speed?
Why is a force directed toward the center
necessary for circular motion?
Is inertia a force? Explain.
What is gravitational force?
What is Newton’s Law of Universal Gravitation?
What is “G” and what does it equal?
A 90.0 kg person stands 1.00 m from a 60
kg person sitting on a bench nearby. What is the magnitude of the
gravitational force between them?
Mars has a mass of about 6.4 x 10^23 kg,
and its moon Phobos has a mass of about 9.6 x 10^15 kg. If the magnitude
of the gravitational force between the two bodies is 4.6 10^15 N, how far
apart are the planet and moon?
