The branch of physics that studies "How objects move" without reference to forces is __ Dynamics Circular Kinematics Nuclear

Which choice is a valid way to construct a motion diagram? Add together the average speeds of the various objects in motion Take a series of photographs at equal time intervals of a moving object, perpendicular to the direction of motion; overlay the images to see how the position changes with time. Draw vectors to represent the speeds involved. Add vectors in a head-to-tail manner to determine the resultant vector

When a fixed amount of ideal gas goes through an isochoric (constant volume) expansion, its pressure must increase its internal (thermal)energy does not change its temperature must increase no heat enters or leaves the gas the gas does no work

Hubble's Law has led physicists and astronomers to the hypothesis that the universe is expanding. True False

Newton determined that the force of gravity on an object is proportional to its mass causing its mass to be canceled out (Newton's second law) and resulting in a constant acceleration. If the laws of physics are universal, then Newton should be able to apply his discoveries about gravity on Earth to the motion of the planets in our Solar System. Newton's third law says that for every force there is an equal reaction force in the opposite direction. What does this imply about the force of gravity associated with a person standing on the Earth? Choose one: A. The force of gravity on the person cancels out to zero. B. The Earth's gravity pulls downward on the person but also pushes upward on them. C. The Earth's gravity pulls downward on the person, and the person's gravity pulls upward on the Earth. D. There is twice as much gravitational force on the person than there would be if it weren't for Newton's third law.
