Newton's Laws of Motion

What is the other name for Newton's First Law of Motion?

• The other name for Newton's First Law of Motion is the Law of Inertia.

• The Law of Acceleration

• The Law of Conservation of Energy

• The Law of Gravity

State Newton's Second Law of Motion.

• The force acting on an object is equal to the acceleration of the object divided by its mass.

• The force acting on an object is equal to the mass of the object added to its acceleration.

• The force acting on an object is equal to the mass of the object multiplied by its acceleration.

• The force acting on an object is equal to the mass of the object divided by its acceleration.

According to Newton's Third Law of Motion, for every action, there is an equal and opposite ____________.

• acceleration

• velocity

• force

• reaction

What is the tendency of an object to resist a change in its motion called?

• Friction

• Velocity

• Inertia

• Acceleration

What is the formula to calculate force?

• Force = mass / acceleration

• Force = mass x acceleration (F = ma)

• Force = mass + acceleration

• Force = mass - acceleration

What is the unit of force in the International System of Units (SI)?

• Kilogram (kg)

• Newton (N)

• Meter (m)

• Second (s)

What is the relationship between force and acceleration according to Newton's Second Law of Motion?

• According to Newton's Second Law of Motion, the relationship between force and acceleration is that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

• The relationship between force and acceleration is that force is equal to the square of acceleration

• The relationship between force and acceleration is that force is directly proportional to velocity

• The relationship between force and acceleration is that force is inversely proportional to acceleration

What is the net force acting on an object if it is accelerating at a rate of 5 m/s^2 with a mass of 10 kg?

• The net force is 50 N.

• The net force is 10 N.

• The net force is 100 N.

• The net force is 25 N.

What is the effect of applying a greater force on an object's acceleration?

• The object's acceleration will decrease.

• The object's acceleration will increase.

• The object's acceleration will become negative.

• The object's acceleration will remain the same.

Explain the concept of action and reaction in Newton's Third Law of Motion with an example.

• When a person pushes against a wall, the wall exerts a greater force back on the person

• In Newton's Third Law of Motion, action and reaction forces are always unequal

• In Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. For example, when a person pushes against a wall, the person exerts a force on the wall, and the wall exerts an equal force back on the person.

• The concept of action and reaction in Newton's Third Law of Motion only applies to objects in motion
