If Earth's radius somehow decreased with no change in mass, your weight would a
stay the same.
b

c
increase.

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

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