Newton 1st and 2nd Laws

What is Newton's first law of motion?

• An object will accelerate if no force is acting on it

• An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

• An object will stop moving if no force is acting on it

• An object will change direction if no force is acting on it

According to Newton's second law, what is the relationship between force, mass, and acceleration?

• F = ma

• F = m/a

• F = ma^2

• F = am

Explain the concept of inertia as described by Newton's first law.

• Inertia is the tendency of an object to always move in a straight line.

• Inertia is the resistance of an object to changes in its shape.

• Inertia is the tendency of an object to resist changes in its state of motion.

• Inertia is the ability of an object to speed up without any external force.

How does Newton's first law relate to objects at rest and in motion?

• Newton's first law explains that objects in motion stop immediately

• Newton's first law states that objects at rest move at a constant speed

• Newton's first law explains that objects at rest stay at rest and objects in motion stay in motion unless acted upon by an external force.

• Newton's first law only applies to objects in space

What is the formula for calculating force based on Newton's second law?

• F = m^2

• F = mv

• F = ma

• F = mc^2

Give an example of how Newton's second law can be applied in everyday life.

• Watching TV

• Pushing a shopping cart

• Riding a bike

• Cooking a meal

Discuss the significance of Newton's laws in the field of physics.

• Newton's laws are significant in physics as they form the basis for classical mechanics, allowing for the calculation of forces, accelerations, and motions of objects.

• Newton's laws are based on astrology rather than science

• Newton's laws are irrelevant in physics

• Newton's laws only apply to biological systems

What are some real-world applications of Newton's first and second laws?

• Cooking recipes, gardening techniques, and weather forecasting

• Pet grooming, bicycle repair, and origami art

• Car safety features like seat belts and airbags, rocket propulsion, and sports performance analysis

• Fashion design, interior decorating, and music composition

Which of the following scenarios best illustrates Newton's First Law of Motion?

• A ball rolling down a hill speeds up.

• A car comes to a stop gradually when the brakes are applied.

• A book remains at rest on a table until someone moves it.

• A rocket launches off the ground when its engines fire.

An automobile you are riding in suddenly stops, but you continue to go forward.
