Do objects have to touch for a force to be involved?
No.
Force that opposes the motion of objects that touch as they pass?
Friction
What is a force only exerted when objects touch?
A contact force? The answer really depends on the level of the question. Primary school answer: A pushing or pulling force, or a friction force occur when objects touch. High school answer: Same as above, but 'pushing' and 'pulling' would be replaced with positive and negative. Friction would be defined as a force that opposes motion, and would include air resistance and drag. University answer: Technically, there is no such force, as all forces act at a distance without touching. In fact, objects don't actually 'touch' one another at all. The outer electrons in an object's atoms will repel said electrons from another object's atoms through the electromagnetic force. This only makes it feel like the objects have come into contact with one another, when in fact they haven't.
What is initial force?
action (versus reaction, the opposing force to action). ================
What is the force that opposes the motion of objects that touch as they move pass each other?
Force of push or pull
What force makes objects fall to earth?
Gravity.
What is The force that makes it difficult to push objects?
fricion
Difference between contact force and those actata a distance?
Contact force means that objects need to be in contact for there to be a force. "Action at a distance" means the objects do NOT need to touch one another directly.
What is a contact force?
when two objects need to touch each other to work, an example for a contact force is static electricity. !
The force that makes objects keep traveling in a straight line is?
attraction
The force that makes objects keep traveling in a straight line?
inertia
What is force in physical science?
force is something that makes objects change velocity.
