Unit 7 Forces Vocabulary Terms

What is the definition of Force?

• A push or pull upon an object resulting from the object's interaction with another object

• The energy possessed by a body due to its motion

• The rate of doing work

• The ability to do work

What is the definition of Magnitude?

• Magnitude is the size or extent of something.

• Magnitude is a type of animal.

• Magnitude is a color.

• Magnitude is a type of food.

Balanced Force is defined as:

• Forces that cause a change in the motion of an object

• Forces that do not cause a change in the motion of an object

• Forces that act in the same direction

• Forces that act in opposite directions

Unbalanced Force is defined as:

• a force that does not change the state of motion of an object

• a force that changes the state of motion of an object

• a force that acts in the opposite direction of motion

• a force that is equal in magnitude and opposite in direction

The definition of Net Force is:

• The sum of all forces acting on an object

• The force that opposes motion

• The force due to gravity

• The force exerted by a surface

The definition of Normal Force is:

• The force that acts perpendicular to the surface of contact

• The force that acts parallel to the surface of contact

• The force that acts at an angle to the surface of contact

• The force that acts in the opposite direction of motion

The definition of Applied Force is:

• A force that is applied to an object by a person or another object

• The force that opposes the motion of an object

• The force that acts at a distance

• The force that is exerted by a fluid

Tension is defined as:

• a force that pulls or stretches a material

• a measure of mass per unit volume

• the rate of change of velocity

• the energy stored in an object due to its position

Gravitational Force is defined as:

• The force that attracts any two objects with mass.

• The force that repels objects with mass.

• The energy stored in an object due to its position.

• The force that acts only on objects with charge.

Weight is defined as the force exerted by gravity on an object. Which of the following best describes this concept?
