Newton's Laws of Motion

What is Newton's first law of motion?

• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• An object at rest will start moving on its own

• An object in motion will eventually come to a stop

• An object in motion will change direction without any force

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

• F = m/a

• F = m + a

• F = 2ma

• F = ma

What is the formula for calculating force?

• force = mass + acceleration

• force = mass - acceleration

• force = mass / acceleration

• force = mass x acceleration (F = ma)

State Newton's third law of motion.

• For every action, there is a random reaction

• For every action, there is an equal and opposite reaction.

• For every action, there is a greater and opposite reaction

• For every action, there is no reaction

Give an example of Newton's first law of motion in everyday life.

• A book resting on a table

• A person jumping off a diving board and into a pool

• A car continuing to move forward even after the driver takes their foot off the gas pedal.

• A ball rolling down a hill eventually coming to a stop

If an object has a mass of 10 kg and experiences an acceleration of 5 m/s^2, what is the force acting on it?

• 100 N

• 25 N

• 50 N

• 10 N

Explain the concept of inertia in relation to Newton's first law of motion.

• The concept of inertia is the tendency of an object to change its state of motion without any force acting on it

• The concept of inertia is the tendency of an object to speed up without any external force

• The concept of inertia is the tendency of an object to resist changes in its state of motion, as stated in Newton's first law of motion.

• The concept of inertia is the tendency of an object to move in a circular path

How does Newton's second law of motion apply to a car accelerating on a road?

• The color of the car affects its acceleration

• The force applied by the car's engine causes the car to accelerate, in accordance with Newton's second law of motion.

• The number of passengers in the car affects its acceleration

• The type of music playing in the car affects its acceleration

What are the units of force according to the International System of Units (SI)?

• Kilogram (kg)

• Meter (m)

• Second (s)

• Newton (N)

Describe an example of Newton's third law of motion in action.

• When a person sits on a chair, the chair pushes them down

• When a person walks, they push back on the ground with their foot (action), and the ground pushes them forward (reaction).

• When a ball is thrown in the air, it keeps moving up without any force acting on it

• When a car accelerates, the engine pushes the car forward
