Force is:

• A push or pull that can change the shape or motion of an object.

• The total of all forces acting on an object.

• Forces that are equal in size but opposite in direction resulting in a net force of 0.

• Forces that are not equal in size or not opposite in direction resulting in a net force greater than 0.

Contact Forces are:

• A push or pull that can change the shape or motion of an object.

• Forces that require objects to be in direct contact.

• Forces that are equal in size but opposite in direction resulting in a net force of 0.

• Forces that do not require objects to be in direct contact.

Field (Non-Contact) Forces are:

• A push or pull that can change the shape or motion of an object.

• Forces that require objects to be in direct contact.

• Forces that are equal in size but opposite in direction resulting in a net force of 0.

• Forces that do not require objects to be in direct contact.

Force is a vector.

• True

• False

The upward force of support applied to an object by the object it is sitting on.

• Net Force

• Normal Force

• Frictional Force

The force applied by friction as one objects slides over another.

• Net Force

• Normal Force

• Applied Force

• Frictional Force

The force applied by a rope, string, or cable on an object.

• Tension Force

• Gravitational Force

• Shear Force

• Air Resistance
