Abapo Quiz #2

While studying Newton's laws of motion, Margie and her lab partner were tasked with determining the relationship between mass and force. They placed four different masses on a table and pulled them using a spring scale. The table shows the different masses used in the experiment and the force required to pull each mass.
The students concluded that more force was required to pull heavier objects. What comment would you make regarding this conclusion?

• No clear relation can be observed between mass and force from the data.

• There is a direct proportion between the mass and force listed in the table.

• There is an inverse proportion between the mass and force listed in the table.

• It cannot be determined until they consider the force of friction on the movement.

Remember, the girls are studying Newton's 2nd law: F = ma. The teacher asked the girls to hypothesize about the acceleration in each one of the four trials. Then they would use their data to calculate "a" or acceleration in the formula. Help them out. What would they hypothesize about the value of "a" in this experiment?

• The greater the force, the greater the acceleration.

• The acceleration would decrease as the mass increased.

• In all four trails, the acceleration would be the same.

• The acceleration would increase as the force increased.

Seat belts have been a requirement in vehicles for decades. They prevent injuries and reduce fatalities during car crashes that involve collisions while the car is in motion. Which of these concepts explains why seat belts are effective against injuries due to car collisions? Select THREE that apply.

• Seat belts act as an unbalanced force against a body's inertia.

  
  

• Seat belts prevent collisions between human bodies and the windshield.

  
  

• Seat belts prevent an object in motion from continuing to move forward.

  
  

• Seat belts increase the momentum of the vehicle but not the person within the vehicle.

  
  

• Seat belts prevent an object in a circular motion will continue to move in a circular motion.
