A student observes that increasing the mass of an object increases the force needed to move it. What scientific law best explains this?
Correct!
Wrong!
Newton’s Second Law explains the relationship between force, mass, and acceleration.
A ball is thrown straight up. What is the direction of its acceleration at the top of its path?
Correct!
Wrong!
Acceleration due to gravity is always downward, even at the peak of motion.
Why does a metal spoon feel colder than a wooden spoon at the same room temperature?
Correct!
Wrong!
Metal conducts heat better, drawing heat away from the skin faster.
If you double the velocity of an object, what happens to its kinetic energy?
Correct!
Wrong!
Kinetic energy increases with the square of the velocity.
Which situation best demonstrates the law of conservation of momentum?
Correct!
Wrong!
In a collision, momentum is transferred, not destroyed.
What type of energy is stored in a compressed spring?
Correct!
Wrong!
A compressed spring stores potential (elastic) energy.

A mirror reflects light to form a clear image. Which principle does this demonstrate?
Correct!
Wrong!
Reflection occurs when light bounces off a surface at an angle equal to the incident angle.
What happens to the current in a circuit if the resistance increases while voltage stays the same?
Correct!
Wrong!
Ohm's Law states current is inversely proportional to resistance.
Why does a helium balloon rise in air?
Correct!
Wrong!
Helium is less dense than air, creating an upward buoyant force.
