Conceptual physics Study Questions with Answers

Conceptual physics Study Questions with Answers newtons first law states - Answer-object motion stay in motion and an object at rest at rest the SI unit of force is newtons - Answer-true an object is at equilibrium when there are equal or no forces acting on it - Answer-true what is mass - Answer-quantity of matter what is newtons first law - Answer-an object at rest will stay at rest unless acted upon by another force what is equilibrium - Answer-a state in which opposing forces or influences are balanced object will keep doing what its doing at a constant speed unless force is acted upon it - Answer-inertia what are some examples of vectors - Answer-displacement,velocity,acceleration what is force - Answer-push or pull what is net force - Answer-the sum of all force acting on an object a vector is a quantity with magnitude and direction represented by arrow that points in its direction - Answer-true what is mass - Answer-the measurement of the amount oa material in an object an object that has lots of inertia will want to - Answer-stay in motion and remain at rest when at rest an example of inertia would be - Answer-falling down on the bus when the bus driver slams on the breaks force is - Answer-push or pull newtons first law is that objects in motion want to stay in motion and objects at rest want to stay at rest - Answer-true one kilogram weighs 9.5 newtons - Answer-true mass is a measure of volume - Answer-true acceleration occurs when an object - Answer-speeds up, slows down,changes direction as an object falls freely in vacuum - Answer-velocity increases, acceleration increases suppose an object is in free fall. each second the object falls - Answer-a larger distance than in the second before what are you looking at when you look at a speedometer - Answer-instantaneous speed a posible unit of distance is - Answer-miles, light years, kilometers The horizontal component of motion ________ is jjst like the horizontal motion of a ball rolling freely along a level surface with out friction - Answer-Projectile The _________ component of a projectiles velocity is like the motion for a freely falling object - Answer-Vertical The resultant of two ______ vectors is the diagonal of a rectangle constructed with the two vectors as sides - Answer-Perpendicular A unit of acceleration is meters per second - Answer-False Momentum is _______ in motion - Answer-Inertia To change momentum you must except a force - Answer-True An object at rest had no momentum - Answer-True Newton first law is called law of inertia - Answer-True Momentum is related to Newton's first law - Answer-True When the net force is zero the forces on an object are balanced - Answer-True The SI units for force are - Answer-Newtons According to Newton's law of motion a moving object that is not acted on by an unbalanced force will - Answer-Remain in motion
