How do you determine whether a point is on a given line or not?
Substitute the coordinates of the point into the equation of the line. If the equation is still valid then the point is on the line; if not then it is not.
How can you determine whether a point is a solution to system of equations?
You substitute the coordinates of the point in the equation. If the result is true then the point is a solution and if it is false it is not a solution.
What is the standard unit of momemtum and impulse?
The units for impulse are kg.m/s. This is because impulse= (final momentum) -(initial momentum) and the units for momentum are kg.m/s.
What can be calculated for a distance-time graph?
Here are some things that can be determined from a distance-time graph:Total distance travelled, at a particular time.Average velocity at a particular time (take the distance at that point and divide by the elapsed time).If you can determine the slope at a particular point, then you can determine instantaneous velocity.You can tell the direction that the object is travelling: away from the starting point (positive slope) or toward the starting point (negative slope).* * * * * If you can determine the second derivative of the graph, you can calculate the instantaneous acceleration as well.
What is needed to determine a line?
Two points determine a line. Also there is one and only line perpendicular to given line through a given point on the line,. and There is one and only line parallel to given line through a given point not on the line.
