4. HOTS-Balanced and unbalanced forces

When the forces are equal and opposite, the mass numberheat energyair pressurenet force is zero, so the object remains at meltrestjumpspin or moves with random speedconstant velocitychanging massfalling force. For example, a box lying on the floor may stay still because gravity and the floor’s support force are balanced. If a person starts to smellcolourtastepush the box, an extra force is added. When this push becomes greater than frictionchargegravity lampvolume, the forces are no longer equal. Then the object experiences force meterdensityaccelerationpressure and begins to move. If the push and friction become equal again while moving, the box may continue with colourful motionhot motionbroken movementsteady motion. This shows that forces on an object can change over colourtimesmellwidth. Therefore, the same object may switch between balanced and unbalanced force conditions.
