Answer:
‘many parts’
Explanation:
I remember learning this in last year AP Chemistry
Answer:
an opposite reaction
Earth's gravity is still pulling down on the rocket. When a rocket burns propellants and pushes out exhaust, that creates an upward force called thrust. To launch, the rocket needs enough propellants so that the thrust pushing the rocket up is greater than the force of gravity pulling the rocket down.
Answer:
The correct answer is - 4.9 kg x m/s^2.
Explanation:
The weight of any object is the mass of the object in specific gravity applied to the object. It can be represented by the F=ma where F is the force applied on the earth by the gravity (a) and mass of the object (m).
Solution:
F = ma
F = 0.5*9.8 kg x m/s^2.
= 4.9 kg x m/s^2.
Kinetic Energy which relies on an objects mass and velocity and Potential Energy which relies on the height of the object
