Mass differs from weight in that:

An arrow is drawn back so that 50 Joules of potential energy is stored in the stretched bow and string. When released, the arrow will have a kinetic energy of ____ Joules.

True or False: If object A with electric charge 26 nC attracts object B with electric charge 52 nC, then object B attracts object A with the same force.

The displacement versus time for a certain particle moving along the x axis is shown. The average velocity in the time intervals  0 to 2 s is :

A force on a particle is conservative if:

An object sits on a frictionless surface. A 16-N force is applied to the object, and it accelerates at 2.0 m/s2. What is the mass of the object?

A car rounds a 20-m radius curve at 10m/s. The magnitude of its acceleration is:

True or False: Electric forces between two charged objects increases with increasing quantity of charge on the objects.

If the net work done on an object is zero, then the object’s kinetic energy

A driver, traveling at 22 m/s, slows down her 2000 kg car to stop for a red light.  What work is done by the friction force against the wheels?
