It has only magnitude of body and not indicate the direction of body.Example. electric potential force.
The heavier it is the more frictions it creates sliding on the floor. this make more kinetic energy.
Answer:
C. 750 N. left
Explanation:
let the force to the right be positive, and the left be negative
Step one:
given
mass of crate m= 500N
1450N force left
Frictional force of 200 N -----this opposes the motion
500 N opposing force to the right
The net force is equal to the summation of all the forces in Newton
Net force= -1450+200+500
Net force=-750N
The direction is right
Answer:
B) The total number of atoms does not change, so mass is conserved in the reaction.
Explanation:
According to the <u><em>Law of Conservation of Mass</em></u>, no matter can ever be created or destroyed. The number of atoms does not change, thus the mass does not change.
Answer:
The angular displacement is not a length (not measured in meters or feet), so an angular displacement is different than a linear displacement. ... As the object rotates through the angular displacement phi, the point on the edge of the disk moves distance sa along a circular path.
