An object moves in a circular path with constant angular speed. Compare the direction of the object's tangential velocity vector to its centripetal acceleration vector.
A) Both vectors point in the same direction
B) The vectors point in opposite directions
C) The vectors are perpendicular
D) Impossible. The acceleration is zero.
Two objects with masses m1 and m2 are original a distance r apart. The magnitude of the gravitational force between them is F. if BOTH masses are doubled, and the distance changed to 4r, what is the magnitude of the new gravitational force between them?
A) F/16
B) F/4
C) 16F
D) 4F

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity and acceleration vectors? The velocity and acceleration vectors point in opposite directions. The velocity and acceleration vectors are perpendicular. The velocity vector points in a direction tangent to the circular path. The acceleration is zero. The velocity vector points toward the center of the circular path. The acceleration is zero. The velocity and acceleration vectors point in the...
An object of mass m moves at a constant speed v in a circular path of radius r.
An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...

Two thin hollow plastic spheres, about the size of a ping-pong ball with masses ( 0.004 kg) have been rubbed with wool. Sphere 1 has a charge -4 × 10-9 C and is at location < 0.47, -0.29, 0 > m. Sphere 2 has a charge -9 × 10-9 C and is at location < -0.42, 0.43, 0> m. It will be useful to draw a diagram of the situation, including the relevant vectors. (a) What is the relative position...

To understand two different techniques for computing the torque on an object due to an applied force.Imagine an object with a pivot point p at the origin of the coordinate system shown (Figure 1). The force vector F⃗ lies in the xy plane, and this force of magnitude F acts on the object at a point in the xy plane. The vector r⃗ is the position vector relative to the pivot point p to the point where F⃗ is applied.The torque on the...
