Yes.
Yes, gravity, friction, and elastic forces can all act on an object simultaneously. Gravity is a force that pulls objects toward each other, friction resists the motion of objects sliding against each other, and elastic forces occur when an object is stretched or compressed and then returns to its original shape.
During an elastic collision with a stationary object, the object will bounce back with the same speed and energy as the incoming object, without any loss of kinetic energy.
When two forces act in the same direction on an object, the forces will add together to create a stronger net force. This will result in an acceleration of the object in the direction of the forces.
No. A balanced group of forces has the same effect on an object as no force at all.
If forces on an object are unbalanced, the object will accelerate or decelerate. If forces on an object are balanced, the object will stay still or keep moving with the same velocity.
When two or more forces affect an object at the same time it creates a net force.
When two forces are acting on an object in the same direction, we combine them by adding their magnitudes together to find the net force acting on the object.
Balanced forces will not change the velocity - speed and direction - of a moving object. the object will continue to move in the same way.
A spring can be both a potential or a kinetic force. When pulled it contains potential force. When it forces an object upwards it contains kinetic energy. The same as if it forces an object to come down i.e return to its natural position. A spring is often referred to as a Helix.
The sum of the forces must be zero. More precisely, "the forces on an object are balanced" means the same as "the vector sum of the forces acting on an object is equal to zero".
