type of forces

What is force usually referred to as?

• The pull or push exerted upon an object as it interacts with another object.

• The weight of an object

• The speed of an object.

• The size of an object.

What causes a contact force?

• An interaction that brings about a direct physical contact between two objects.

• An interaction between two objects that are far apart.

• The gravitational pull between two objects.

• The magnetic attraction between two objects.

What is the normal force?

• The force exerted upon an object by the surface with which it is in contact with, perpendicular to the surface.

• The force exerted upon an object by a surface, parallel to it.

• The pulling force exerted upon an object by a cord it is attached to.

• The force opposite the relative motion of the object as it moves through the air.

What is the friction force?

• The force exerted upon an object by the surface with which it is in contact with, perpendicular to the surface.

• The force exerted upon an object by a surface, parallel to it.

• The pulling force exerted upon an object by a cord it is attached to.

• The force opposite the relative motion of the object as it moves through the air.

What is the tension force?

• The force exerted upon an object by the surface with which it is in contact with, perpendicular to the surface.

• The force exerted upon an object by a surface, parallel to it.

• The pulling force exerted upon an object by a cord it is attached to

• The force opposite the relative motion of the object as it moves through the air.

What is the air resistance force?

• The force exerted upon an object by the surface with which it is in contact with, perpendicular to the surface.

• The force exerted upon an object by a surface, parallel to it.

• The pulling force exerted upon an object by a cord it is attached to.

• The force opposite the relative motion of the object as it moves through the air.

What is the applied force?

• The force applied to an object by a person or another object.

• The force exerted upon an object by the surface with which it is in contact with, perpendicular to the surface.

• The force exerted upon an object by a surface, parallel to it.

• The pulling force exerted upon an object by a cord it is attached to.

What is the spring force?

• The force applied to an object by a person or another object.

• The force exerted upon an object by the surface with which it is in contact with, perpendicular to the surface.

• The force exerted by a compressed or stretched spring to an object.

• The pulling force exerted upon an object by a cord it is attached to.

What are noncontact forces?

• Forces that act between objects that are distant and are separated by vacant space.

• Forces that act between objects that are in direct contact.

• Forces that act between objects that are moving at high speeds.

• Forces that act between objects that are stationary.

What is the magnetic force?

• The force responsible for the repulsion or attraction between moving charged particles.

• The force exerted by one electric charge to another, both for stationary and moving charges.

• The force responsible for attracting two objects that have mass.

• The force that keeps the atoms from separating together due to the electric force from the repulsion of the protons.
