Newton's Laws of Motion(TEKS 8.7B) Quiz

When two soccer players with different masses collide with the same amount of force while playing soccer, Newton's laws of motion are demonstrated. The first law is seen as the players' motions change by the unbalanced force of the other player running into them. Newton's third law of motion is seen as the players bounce back away from each other. How is Newton's second law of motion demonstrated in this situation?

• The smaller player accelerates backwards faster due to his smaller mass.

• The inertia of the soccer ball causes the smaller player to change direction.

• The smaller player hitting the larger player is the action force, and the larger player hitting back is the reaction force.

• The smaller player balances the force from the larger player and stops moving.

Which of the following is NOT a description of how Newton's laws of motion affect tectonic plate activity?

• Because tectonic plates are massive slabs of rock, a great amount of force is required for them to move.

• One plate pushes against a second plate and the second plate pushes back in the opposite direction with the same amount of force. The plates pushing against each other form mountains.

• All tectonic plates will continue to stay at rest until balanced forces act on them.

• Tectonic plates will continue moving at a constant speed in the same direction until acted upon by an unbalanced force.

Students are studying Newton's laws and are asked to design a roller coaster ride to demonstrate how the laws apply. Students use a marble to test their design by placing it at the highest point and letting it go to begin the ride. They then observe how the marble travels down the track before coming to a stop. Students understand that Newton's Law of Inertia is observed at the top of the ride when gravity acts on the marble to start it moving, but are not sure how Newton's second law applies. Which of the following statements BEST explains how Newton's second law applies?

• Friction acts on the marble to change the force that is accelerating it, causing it to speed up faster.

• The force acting on the marble increases the acceleration until balanced forces are applied.

• The action force is the gravity pulling on the marble and the reaction force is the marble pushing on the roller coaster track.

• The force pulling the marble down is from the acceleration due to gravity acting on the marble's mass.
