The mass and related weight on the respective objects on four different planets is
4 kg, 40n, earth
6 kg, 24n, mars
2 kg, 50n, jupiter
4 kg, 36n, venus
a) based on the information given, explain why the gravitational force on earth is stronger than on venus.(3%)
b) explain the relationship between the weight and the gravitational force of the planet on the object.(2%)
c) predict what will happen if the mass of the four planets is the same(3%)

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i. e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that

The ideal gas model is valid if which of the following conditions is true? the gas density is low. the gas density is high. the temperature is low. the temperature is high. the gas density and the temperature are low. the gas density and the temperature are high. the gas density is high and the temperature is low. the gas density is low and the temperature is high.
