A ball is thrown straight up. At what point does the ball have the most energy? - -Everywhere; the energy of the ball is the same at all points. -A man pushes a block up an incline at a constant speed. As the block moves up the incline - -its potential energy increases and its kinetic energy remains the same. -You push very hard on a heavy desk, trying to move it. You do work on the desk - -only if it starts moving -When the speed of your car is doubled, by what factor does its kinetic ...

An object can move even when no force acts on it - -True -If an object isn't moving, no external forces act on it - -False -If a single force acts on an object, the object accelerates - -True -If an object accelerates, at least one force is acting on it - -True -If an object isn't accelerating, no external force is acting on it - -False -If the net force acting on an object is in the positive x-direction, the object moves only in the positive x-direction - -False -No force of...

Uniform motion -Motion where equal displacements occur during successive equal time intervals. -Constant acceleration -Acceleration that does not change over time. -Instantaneous acceleration -The acceleration of an object at a particular instant of time. -Acceleration due to gravity -The acceleration of an object in free fall resulting from Earth's gravity. -Contact force -A force exerted on an object only when touching it. -Long-range force -A force that acts on an object witho...

Friction always acts in a direction _______ to the motion - -opposite -The ________ friction force is equal to the product of the coefficient of the kinetic friction and the normal force - -Kinetic -Which is a type of friction you experience as you push a book across a table? - -Kinetic Friction -The net force on an object is zero. What must be true of this object? - -The objects velocity is constant -An object in _______ is motionless or moves with constant velocity - -equilibrium ...

Suppose that the displacement of an object is related to time according to the expression x=Bt^2. What are the dimensions of B? - -L/T^2 -A displacement is related to time as x=Asin(2pift), where A and f are constants. Find the dimensions of A. - -L -The radius of a circle is measured to be (10.4+-0.2)m. Calculate each of the following and give the uncertainty in each value.
