What else can I help you with?
Why is magnetic force a non contact force?
Because it's not necessary for objects to be in contact (touching) in order to feel the magnetic force between them.
What Charged objects do not have to what to exert a force on each other?
Charged objects do not have to physically touch each other in order to exert a force on each other. The force between charged objects can be exerted through electromagnetic fields that extend through space. This force is known as the electrostatic force.
What force has to touch something?
A force needs to be applied in order to touch something. This force can be exerted through physical contact or interaction between two objects, causing them to make contact with one another.
Is pulling a contact force?
Yes, pulling is an example of a contact force because it requires physical contact between two objects in order to exert a force. When you pull an object, you are exerting a force through direct contact with that object.
What must be applied to a objects in order change the objects motion or direction?
A force must be applied to an object in order to change its motion or direction. This force can be in the form of a push or pull exerted on the object. The magnitude and direction of the force applied will determine how the object's motion changes.
Do 2 things have to touch in order to have force between them?
No, two objects do not necessarily have to touch in order for a force to act between them. Forces such as gravitational, magnetic, and electric forces can act over a distance without requiring physical contact between the objects.
Why is magnetic force a non contact force?
Because it's not necessary for objects to be in contact (touching) in order to feel the magnetic force between them.

What must you know in order to tell the gravitational force between two objects?
To calculate the gravitational force between two objects, you must know the mass of each object and the distance between their centers. The force can be calculated using Newton's law of universal gravitation, which states that the force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
What force has to touch something?
A force needs to be applied in order to touch something. This force can be exerted through physical contact or interaction between two objects, causing them to make contact with one another.
Is pulling a contact force?
Yes, pulling is an example of a contact force because it requires physical contact between two objects in order to exert a force. When you pull an object, you are exerting a force through direct contact with that object.
What would you apply in order to change an objects velocity?
force
What must be applied to a objects in order change the objects motion or direction?
A force must be applied to an object in order to change its motion or direction. This force can be in the form of a push or pull exerted on the object. The magnitude and direction of the force applied will determine how the object's motion changes.
What must you know in order to determane the gravitational force between 2 objects?
You need to know . . . -- the mass of each object -- the distance between their centers of mass -- the value of the universal gravitational constant
Does electric force require that objects touch?
No, electric force does not require objects to touch in order to act on each other. Objects with electric charge can exert attractive or repulsive forces on each other even when they are not in physical contact.
Which property must be the same in order to stop the transfer of energy between two objects?
The temperature of the two objects must be the same in order to stop the transfer of energy between them. Energy will transfer as long as there is a temperature difference between the objects.
What force is opposing the buoyant force?
The force opposing the buoyant force is the force of gravity. Gravity pulls objects downward, creating a force that must be overcome by the buoyant force in order for an object to float in a fluid.
