Newtons Laws Of Motion Flashcards
Who developed the Laws of Motion?
Isaac Newton
Newton was a British scientist known for his work in physics and mathematics.
What is the primary concept that Newton discovered related to motion?
Gravitational force
This force pulls objects toward the center of the Earth.
In what year did Newton publish his findings?
1664
This was a significant year for the scientific community.
What does Newton’s first law of motion state?
An object at rest stays at rest and an object in motion stays in motion unless acted upon by a force
This law emphasizes inertia.
What does the term ‘inertia’ refer to?
The resistance of an object to change its state of motion
Inertia is a key concept in Newton’s first law.
Fill in the blank: Newton’s first law states that an object cannot change its motion unless acted upon by a _______.
[force]
What happens to an object when a net force acts on it?
It changes its state of motion
This is a fundamental principle of Newton’s laws.
True or False: Newton’s laws apply only to objects at rest.
False
Newton’s laws apply to both moving and stationary objects.
What is the significance of Galileo’s studies in relation to Newton’s work?
Newton based his laws on Galileo’s studies
Galileo’s work laid the groundwork for Newton’s theories.
What does Newton’s first law of motion state?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force
This law emphasizes the concept of inertia.
What is inertia?
The tendency of an object to resist changes in its state of motion
Inertia is directly related to the mass of the object.
What happens when forces are balanced?
The object remains in a state of motion or at rest
This means there is no net force acting on the object.
What is the relationship between force and acceleration according to Newton’s second law?
A larger force results in greater acceleration
This law can be summarized by the equation F=ma (Force = mass x acceleration).
What occurs when forces are unbalanced?
The object accelerates
Even a small force can cause acceleration if the forces are not balanced.
Complete the statement: Newton’s third law states that for every action, there is a _______.
equal and opposite reaction
This law highlights the interaction between two objects.
What does Newton’s second law focus on?
The net force acting on a single object
It explains how the net force affects the motion of that object.
True or False: An object will continue moving in a straight line at constant speed unless acted upon by an unbalanced force.
True
This is a direct implication of Newton’s first law.
What is required to change the motion of a more massive object?
A greater force
This is due to the object’s inertia, which resists changes in motion.
What is the term for the total force acting on an object?
Net force
Net force is the vector sum of all individual forces acting on an object.
Define surface area.
The total area that the surface of an object occupies
Surface area is important in various applications, including physics and engineering.
What does the term ‘applied force’ refer to?
A force that is exerted on an object by a person or another object
Applied force can cause an object to move or change its state of motion.
Fill in the blank: The resulting motion of an object depends on the _______.
Net force
The net force determines how an object will move according to Newton’s laws of motion.
True or False: Resistance is a force that opposes motion.
True
Resistance can occur due to friction, air resistance, or other factors.
What is the role of friction in motion?
It opposes the motion of objects in contact
Friction can be beneficial, such as providing traction, or detrimental, such as causing wear.
Static equilibrium
In static equilibrium, the net force acting on the object is zero.
Fill in the blank: Objects that are in motion will continue to move at a constant velocity unless acted upon by a _______.
Net force
This principle is derived from Newton’s first law of motion.
What is meant by ‘mechanical shape’?
The physical configuration of an object that affects how forces act upon it
Mechanical shape can influence the dynamics of motion and resistance encountered.
