A block of mass m with a given initial speed slides down a rough incline with constant speed. If a similar block that has a mass of 4m were placed on the same incline with the same initial speed, it would

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
