###### Answer: Yes the bowling ball is in equilibrium because ΣF = 0.

Tue Jan 15 2002 13:30:00 GMT-0500 (Eastern Standard Time) · The ball travels in the air and there is no net force upon it. To the stationary observer the ball follows a straight-line path so there is no problem squaring this trajectory with zero net force. However the rotating observer sees a curved path.

The first law states that an object at rest will stay at rest and an object in motion will stay in motion unless acted on by a net external force.Mathematically this is equivalent to saying that if the net force on an object is zero then the velocity of the object is constant . ∑ = ⇔ = Newton’s first law is often referred to as the principle of inertia.

The Newton’s cradle is a device that demonstrates the conservation of momentum and the conservation of energy with swinging spheres. When one sphere at the end is lifted and released it strikes the stationary spheres transmitting a force through the stationary spheres that pushes the last sphere upward.The last sphere swings back and strikes the nearly stationary spheres repeating the …

Hooke’s law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is F s = kx where k is a constant factor characteristic…
