Students are investigating how mass affects the force needed to move an object. They attached a wooden block to a spring scale and placed a 10 g mass on top of the block and pulled it 50 cm across the table.
Which of the following changes to their setup would result in a larger force reading on the spring scale?

A.) sliding the block 60cm
B.) attaching a larger spring scale
C.) using a 20g mass
D.) using a circular piece of wood

the total distance traveled by the car is

30km + 49km = 79 km .

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

glad that
