Year 10 Science- Physics Exam Revision
Questions and Answers
what is distance? - Answer-the actual length of path covered or how far an object
travels
what is displacement? - Answer-the change in position and direction of an object, does
not take into account all movement in between, just start and end positions
what is a vector quantity? - Answer-a vector quantity includes both magnitude and
direction, and is represented with arrows that can be added and subtracted
what is a scalar quantity? - Answer-a scalar quantity includes only magnitude
what does the gradient of a position time graph represent? - Answer-velocity
if an object on a position time graph is moving northward and then proceeds to move
into the negative y axis, what direction is it now going? - Answer-the object is now
moving south of starting position
what is another name for a position time graph? - Answer-displacement time graph
what is the worded formula for velocity? - Answer-displacement divided by time
what unit is velocity measured in? - Answer-metres per second
what is velocity? - Answer-the rate at which displacement changes
when a line plateaus on a position time graph, what is the object doing? - Answer-the
object is at rest
what does speed measure? - Answer-the rate at which distance is covered
what does the area under a speed time graph give? - Answer-distance travelled
what is the worded formula to find speed? - Answer-distance divided by time
what is acceleration? - Answer-the rate at which velocity changes
what unit is acceleration measured in? - Answer-metres per second squared
what is the worded formula for velocity? - Answer-displacement divided by time
on what graph is the gradient acceleration? - Answer-velocity time graph
