πŸ™.) Which term describes how far an object has traveled from its original location?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: displacement

𝟚.) What would the position-time graph look like for an object that remains still over time?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: a horizontal line

πŸ›.) Which statement about forces is correct?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: Forces have both magnitude and direction.

𝟜.) What is a force?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: a push or a pull on an object

𝟝.) Which situation describes a non-contact force acting on an object?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: a person pouring water out of a pitcher

𝟞.) In which of these situations would an object have the greatest momentum?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: An object with a large mass is moving quickly.

𝟟.) A force applied to an object at rest causes the object to move. According to Newton’s first law, what must be true of the force?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: The force is unbalanced

𝟠.) Shot put is a track-and-field event in which athletes propel a metal shot, or ball, by pushing it away from their shoulder. In junior events, shots of different sizes are used for different categories of competitors.

πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: textbook

πŸ™πŸ˜.) A tennis player hits a ball with a racket. How do the racket and the ball act on each other?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: The racket and the ball exert forces on each other with equal strength and in opposite directions.

πŸ™πŸ™.) What does Newton’s third law of motion state?
πŸ…°πŸ…½πŸ†‚πŸ††πŸ…΄πŸ†: For every action, there is an equal reaction in the opposite direction.
