What is the term for the natural inclination of an object to maintain its state of rest or uniform motion in a straight line?

• Friction

• Inertia

• Motion

• Force

Which of the following best explains the subtle distinction between Newton’s First Law of Motion and Galileo’s assertion about force and horizontal motion?

• Newton’s First Law states that an object at rest remains at rest unless acted upon by an external force, while Galileo believed that force is always required to maintain motion.

• Newton’s First Law applies only to objects in space, whereas Galileo’s assertion applies to objects on Earth.

• Newton’s First Law generalizes Galileo’s idea by stating that an object in motion remains in motion with constant velocity unless acted upon by an external force.

• Newton’s First Law contradicts Galileo’s assertion because it states that motion requires a continuous application of force.

A car is initially at rest, then accelerates forward in a straight path and eventually comes to a stop. What types of motion does the car experience during this sequence?

• Place a rough carpet under the furniture to increase friction.
  

• Lift the furniture entirely off the floor to eliminate friction.

• Use furniture sliders or wheels to reduce friction.

• Push the furniture at an angle to apply more force and increase friction.

Consider a scenario where a soccer ball is rolling across a field and eventually comes to a stop. Break down the factors that caused the ball to stop and explain how these factors demonstrate Newton’s First Law of Motion. Which of the following factors best explains why the ball stopped?"

• There were no forces acting on the ball.

• Gravity acted on the ball, pulling it down to the field.

• Friction between the ball and the ground slowed it down.

• The ball’s inertia changed, causing it to stop on its own.

Friction is a property of an object that resists any change in its motion.' Based on your understanding of Newton’s laws and the nature of forces, determine whether this statement is accurate. Choose the best option and justify your choice.

• True because this would imply that friction is an inherent property of objects, but friction is not something an object inherently possesses.

• False because Friction is an external force that acts between two surfaces, not a property of the object itself.

• Maybe because this is vague and not accurate because scientific concepts require clear explanations.

• A and B because this contradicts itself and cannot be valid because friction cannot both be and not be a property at the same time.
