simple harmonic motion – the pendulum and the spiral spring
... they will maintain this motion, but at a higher frequency than they would oscillate if uncoupled. These two possibilities are called the normal modes of the system, and are illustrated in Figure 3. When the pendula are not identical there are still two normal modes, but the motions are more complica ...

... these forces are related by Newton’s 3rd law (Third law pairs). An example of a third law pair is as follows: If you push the cart, there is a force from your hand on the cart. There is also a force from the cart on your hand. These two forces are a Newton’s third law pair. Newton’s third law pairs ...

Multiple Choice 3 with Answers
... D. if its velocity is large. Answer C (Acceleration is defined as a change in velocity and velocity has both magnitude (speed) and direction. Thus change of speed and/or direction is acceleration). 2. If the mass of an object in free fall is tripled, its acceleration A. triples B. increases nine tim ...

Centripetal Force
... Swing a mass around in a circle on the end of a string. Do you feel a force pulling your hand outwards? This is often called a “centrifugal force.” You might have heard that centrifugal forces cause circular motion, but this is not good physics! ...

What is the minimum time taken by the object to cover a displacement ‘s’ if it starts from rest and finally comes to rest? Solution : The minimum time would be when the acceleration is at maximum and de ...
