Newton's Laws of Motion Quiz

Arjun and Sophia are playing a game of push and pull. Samuel, observing them, notices that it's harder to start moving Sophia's heavier sled than Arjun's lighter one. What is Samuel observing?

• Samuel is observing Arjun's tendency to accelerate.

• Samuel is observing Sophia's lack of motion.

• Samuel is observing Arjun's ability to move quickly.

• Samuel is observing the resistance to changes in motion, also known as inertia.

Anika, Aria, and Kai are studying physics. They are discussing Newton's second law of motion. They want to understand the relationship between force, mass, and acceleration when Anika pushes a shopping cart. Can you help them?

• The force Anika applies is inversely proportional to the mass of the cart and its acceleration

• The force Anika applies is directly proportional to the mass of the cart but inversely proportional to its acceleration

• The force Anika applies is directly proportional to both the mass of the cart and its acceleration

• The force Anika applies is directly proportional to the acceleration of the cart but inversely proportional to its mass
