Question 9 2 pts Students explain why they chose a specific material as a liner for the safety helmet. Which of the following best explains the physics behind choosing a specific material as a liner? Select all that apply. For any given object, a larger force causes a larger change in motion. An object's motion will only change if the total force on it is bafanced. The mass of an object determines its change in motion when subject to a force. The greater the mass of the object, the smatler the force noeded to achieve any change in motion. The force exerted by one object on a second object always moves the second object in the opposite direction. Question 10 2 pts You review a report the team has prepared about their investigation.
