Forces and Motion CS

What is the definition of relative position?

• The speed at which an object moves

• The change in an object's position in reference to another object
  

• The force that acts when two surfaces rub against each other

• The amount of space covering the outside of a three-dimensional shape

What is the meaning of frame of reference?

• The speed and direction of an object

• The tendency of an object in motion to stay in motion or an object at rest to stay at rest

• An object to which you can compare an object's position

• A force that acts when two surfaces rub against each other

What does speed measure?

• How fast an object's position changes

• The speed and direction of an object

• The force that acts when two surfaces rub against each other

• The amount of space covering the outside of a three-dimensional shape

What is velocity?

• The change in an object's position in reference to a second object.

• An object to which you can compare an object's position.

• How fast an object's position changes.

• The speed and direction of an object.

What is force?

• The change in an object's position in reference to a second object

• An object to which you can compare an object's position.

• How fast an object's position changes.

• Any push or pull.

What is friction?

• The change in an object's position in reference to a second object.

• An object to which you can compare an object's position.

• How fast an object's position changes.

• A force that acts when two surfaces rub against each other and slows them down.

What is gravity?

• The change in an object's position in reference to a second object.

• An object to which you can compare an object's position.

• How fast an object's position changes.

• A force which makes objects pull toward each other or toward the center of the earth.
  

What is acceleration?

• The change in an object's position in reference to a second object.

• An object to which you can compare an object's position.

• How fast an object's position changes.

• When an object speeds up, slows down, and changes direction.

What is inertia?

• The change in an object's position in reference to a second object.

• The change in an object's position in reference to a second object.

• How fast an object's position changes.

• The tendency of an object in motion to stay in motion or an object at rest to stay at rest.
  

What is surface area?

• The change in an object's position in reference to a second object.

• An object to which you can compare an object's position.

• How fast an object's position changes.

• The amount of space covering the outside of a three-dimensional shape.
