Newton's Laws of Force and Motion

Evelyn, Nora, and Ava are having a debate. Evelyn says that according to Newton's first law of motion, an object at rest will stay at rest unless acted upon by what? Can you help them solve this debate?

• gravity

• external force

• inertia

• friction

Luna, Charlotte, and Abigail are having a friendly debate about Newton's second law of motion. They are discussing what happens to the acceleration of an object when the force acting on it increases. Can you help them settle this?

• The acceleration of the object becomes zero.

• The acceleration of the object remains the same.

• The acceleration of the object increases.

• The acceleration of the object decreases.

Imagine this: Michael and Luna are having a friendly debate about Newton's third law of motion. Michael insists that for every action, there is an equal and opposite reaction. Luna, however, thinks it's something else. According to Newton's third law, for every action, there is an equal and opposite what?

• force

• acceleration

• reaction

• motion

Anika, Olivia, and Jackson are having a debate about Newton's laws. They are trying to figure out which of Newton's laws states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Can you help them out?

• Newton's third law of motion

• Newton's law of universal gravitation

• Newton's second law of motion

• Newton's first law of motion

Imagine Benjamin and Arjun are having a fun science debate. Benjamin says that the force that attracts or repels objects based on their charges is the Magnetic force. Arjun, however, disagrees and says it's a different force. Hannah, being the science whiz, knows the correct answer. Can you help her out? What is the force that attracts or repels objects based on their charges?

• Magnetic force

• Electrostatic force

• Frictional force

• Gravitational force
