Fundamentals of Newton's Laws and Energy

A set of flashcards covering key concepts related to Newton's Laws of Motion and energy principles.

What is Newton's First Law of Motion?

An object will remain at rest or move at a constant speed unless acted upon by an unbalanced force.

What do balanced forces do to an object's motion?

Balanced forces do not change an object's motion.

What happens when unbalanced forces act on an object?

Unbalanced forces can speed up, slow down, or change the direction of an object's motion.

Define Newton's Third Law of Motion.

For every action, there is an equal and opposite reaction between two colliding objects.

What occurs when two objects collide according to Newton's Third Law?

Both objects exert equal and opposite forces on each other.

How does a seat belt function during a collision?

A seat belt restricts the motion of a passenger during a collision.

What is the purpose of crumple zones in vehicles?

Crumple zones absorb impact force during a collision.

How does mass affect kinetic energy?

Greater mass results in greater kinetic energy.

How does speed impact kinetic energy?

Greater speed results in greater kinetic energy.

What happens to potential energy when an object is elevated?

Increasing the height of an object increases its potential energy.

What are the two forms of energy discussed in the notes?

Kinetic energy (energy of motion) and potential energy (stored energy due to position).
