People Window Help pid-5847209-dt-content-rid-22381781_1/courses/PHYS2130001201740/2130Recitation Force and Free Body Diagrams 1. If an object is at rest, can you conclude that there are no forces acting on it? Explain. 2. If a force is exerted on an object, is it possible for that object to be moving with constant velocity? Explain. 3. A constant force applied to an object causes the object to accelerate at 8 m/s2. What will the acceleration of this object be if a. the force is halved? b. the mass is halved? c the force is halved and the mass is halved? d. the force is halved and the mass is doubled? 5017 OrC.. .zip 17.2-2016 5017 OrC.. .zip Canceled MacBook Air

Explanation / Answer

1.No... even though forces are acting,if the resultant force is zero then the body is at rest.

2. No... for single force the body doesn't move with constant velocity.

3. Acceleration a= F/m

a proportional to the Force and inversely proportional to mass

A. If force is halved acceleration is also halved keeping mass constant

B. If mass is halved ...a becomes doubled

C. Force is halved and mass is halved....then acceleration remains constant.

D. Force is halved and mass is doubled....then acceleration becomes 1/4 the of the initial.
