Write how gravity and the mass of the pack affected the motion of the pack when it was thrown at different forces.

A rocket with more mass will speed up more slowly, just as in the horizontal example, but there is another effect. The force of gravity is now acting in the opposite direction to the thrust, so the resultant force pushing the rocket upwards is also less.

The greater the mass of the pack, the heavier the pack becomes (increased weight due to gravity) and the motion of the pack will be reduced. On the other hand, if the mass of the pack is reduced, the pack becomes lighter (reduced weight due to gravity) and the motion will increase.

According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = mg

where;

m is the mass of the object
g is the acceleration due to gravity
F is the applied force

From the equation above, the greater the mass of the pack, the heavier the pack becomes (increased weight due to gravity) and the motion of the pack will be reduced. On the other hand, if the mass of the pack is reduced, the pack becomes lighter (reduced weight due to gravity) and the motion will increase.
