Equal and Opposite but Not Balanced Because action and reaction forces are equal and opposite, you might think
they would cancel out, as balanced forces do. But you would be wrong.
Balanced forces are equal and opposite forces that act on the same object.
That's why they cancel out. Action-reaction forces are equal and opposite
forces that act on different objects, so they don't cancel out. In fact, they often
result in motion. Think about Jerod again. He applies force with his foot to the
ground, whereas the ground applies force to Jerod and the skateboard,
causing them to move forward.
If the forces are equal and opposite, why do they not cancel out?

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
