Forces can only stop objects from moving true or false?
False. Forces can also set stationary objects in motion.
How can forces act on an object without touching?
forces always have to touch an object to affect it because if you lay down a small piece of paper and blow on it its going to move p.s. I'm only a 5th grader
Is it true forces can be added together only if they are acting on different objects?
Yes, it is true
How do balanced forces affect an object that is at rest?
Not at all. The object is at rest only because the forces are balanced.
An unbalanced force will not change an objects motion?
If the forces on an object are unbalanced then the objects motion will change. It will start accelerating in the direction of the resultant force. Only objects that have balanced forces will remain in the same motion (stationary or moving at a constant speed).
Are forces only exerted when objects touch each other?
No...
Can only solid objects exert forces?
Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.
Can forces only affect objects if the object is touched?
I don't think so. The earth doesn't have to touch a rock in order for the force of gravity to pull the rock towards the earth. A magnet doesn't have to touch a paper clip in order to pick it up off the table and pull it all the way to the magnet.

Does gravity affect all or only some of the objects in the universe?
Gravity affects all of the objects in the universe, but then again, gravity doesn't affect the universe.
Does color affect cooling time of objects?
color only affects the cooling time of objects if there is light
Is it true forces can be added together only if they are acting on different objects?
Yes, it is true
How do balanced forces affect an object that is at rest?
Not at all. The object is at rest only because the forces are balanced.
What are contact forces and which forces are contact?
Contact forces are forces that can only have an effect on objects that they touch, such as when you contact a box and apply force to move it. you might apply a contact force to bend, tear, stretch, compress, or twist and abject. Tension force, friction force, and elastic force are examples of contact forces.
An unbalanced force will not change an objects motion?
If the forces on an object are unbalanced then the objects motion will change. It will start accelerating in the direction of the resultant force. Only objects that have balanced forces will remain in the same motion (stationary or moving at a constant speed).
What is the difference between electeical forces and gravitational forces?
-- Electrical force only cares about the charge on two objects, and ignores their mass. Gravitational force only cares about the mass of two objects, and ignores their charge. -- Electrical force can be attractive or repulsive. Gravitational force can only be attractive.
