Answer:
mass- the amount of matter in an object
balance- tool used to measure mass
scale- a tool used to measure weight
weight- the downward pull on an object due to gravity
Answer:
The new planet has more gravity
Explanation:
gravity force = G m1 m2 / r^2
decresing r or increasing the planet mass will increase the force
Explanation:
The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy.
Answer:
density
Explanation:
mecurys is significantly smaller and less massive than earth
