Question
Indicate whether the following statements are always true orcan be false. This is what I have and something is wrong...thecomputer is telling me that I'm wrong, anyone can helpme...???F,T,F,T,FA ball is dropped to the floor and it bounces back. No force isrequired for the ball to bounce back since the ball is"elastic".
In order not to slow down, a motorcycle moving at aconstant velocity needs a small net force applied.
If the acceleration of an object is zero, there are no forcesacting on the object.
When only one force acts on an object, the accelerationof the object can be zero.
If a net force acts on an object, the object's speedwill change.

Explanation / Answer
A ball is dropped to the floor and itbounces back. No force is required for the ball to bounce backsince the ball is "elastic". False,(Normal force from the ground greater thanits weight gets applied.) In order not to slow down, a motorcycle movingat a constant velocity needs a small net force applied.True, caus it just needs a force to change the velocity,assuming that the force is applied in the opposite direction to thedirection of travel If the acceleration of an object is zero, there are no forcesacting on the object. False, the sum of all of theforces is zero but that doesn't mean forces aren't acting. When youstand on the ground, gravity is acting down but the floor is alsopushing upwards. Hence no acceleration but forces areacting. When onlyone force acts on an object, the acceleration of the object can bezero. True, an unbalancedforce leads to an acceleration.
