Graphs and charts are common tools used in science. To interpret graphs, read the axis labels as well as the numbers on the axis. The title should give you some clue as to the purpose of the graph. Next, examine the content. Try to describe the content in words, using “As ____(quantity on the x axis), ____(type of change, such as increases or decreases), ____ (quantity on the y axis) ___(type of change such as increases or decreases).” For example, the graph above could be described, “As time increases from 0 to 8 seconds, the velocity of Billy increases linearly from 0 to about 14 m/s.”…

Increasing space between each domino will decrease its velocity, decreasing the space will increase its velocity. Force at which it hits next dominoes is increased it will take longer for it hit, acceleration is constant, the longer it has to travel, the longer it will take to hit.…
Question 22 (5 marks) An astronaut on the Moon throws a stone from the top of a cliff. The stone hits the ground below 21.0 seconds later. The acceleration due to gravity on the moon is 1.6 ms–2.…

When there is more than one force that acts on an object, the subsequent motion of the object is then determined by the net force acting on the object. The net force is the vector sum of all the forces that are acting on the object.…

Carla and Jenny are arguing about whether or not it is possible to escape the gravitational field of the Earth. Carla shows Jenny the system below where mass mis rE (not the Earth 's radius) distant from Earth and rP (not planet P 's radius) distant from planet P. Carla states that the mass m has escaped if FP on m = FE on M. Which one, if either, is correct, and why?…
