Galileo vs Aristotle

How did Aristotle explain projectile motion?

• Objects move in a straight line due to an external force.

• Projectiles are influenced by an impetus imparted to them.

• Gravity is the sole force acting on projectiles.

• Projectiles move in a circular motion.

What did Galileo’s inclined plane experiments demonstrate about motion?

• Objects of different masses fall at different rates.

• Objects maintain a constant velocity in the absence of external forces.

• The speed of a falling object is directly proportional to its mass.

• Objects accelerate uniformly when subjected to a constant force.

What is an inherent force or power thought to be acquired by a moving object according to Aristotle?

• Impetus

• Inertia

• Free fall

• Force

What did Galileo contribute to the understanding of falling objects?

• Objects fall at different rates based on mass

• Objects maintain a constant acceleration during free fall

• Falling objects follow circular trajectories

• Impetus influences the speed of falling objects

What is Newton’s First Law of Motion?

• Acceleration

• Impetus

• Inertia

• Interaction

Who is the proponent of the three laws of motion?

• Galileo Galilei

• Albert Einstein

• Aristotle

• Isaac Newton

What does Newton’s First Law of Motion state?

• The rate of change of momentum is directly proportional to the applied force.

• Every action has an equal and opposite reaction.

• Force is equal to mass times acceleration.

• An object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity unless acted upon by a net external force.

What Law of Motion states “Every action has an equal and opposite reaction”?

• Law of Inertia

• Law of Interaction

• Law of Acceleration

• Law of Falling bodies

According to Newton’s Third Law of Motion, what happens when you push against a wall?

• The wall pushes back with an equal and opposite force.

• The wall absorbs the force.

• The force applied to the wall is greater than the wall’s reaction.

• The wall moves away from the force.

Newton’s First Law describes inertia, which is the tendency of an object to resist changes in its…?

• motion

• mass

• force

• velocity
