Unit of Acceleration?

m/s2

Unit of Velocity?

m/s

Unit of distance or displacement?

m (Meter)

A movement of an object

Motion

Was an English Mathematician and physicist who made major contributes to science.

Isaac Newton

Newton is best known for creating the three laws of motion and the theory of?

Universal Gravitation

A smaller unit of force is?

Dyne

Forces that reqiure direct contact between interacting bodies is called?

Contact Forces

Forces that do not require direct contact is called?

Non-

This refers to the resistive force that is present in all forms of matter in contact with each other

Friction

is the force that resists the initiation of sliding motion between two surfaces that are in contact and at rest relative to each other.

Static Friction

This is present when there is relative motion between the surface contact.

Kinetic Frictiob

This occurs when one surface rotates as it moves over another w/out sliding nor slipping at one point or area of contact

Rolling Friction

An object will continue to be in the state of rest or in a state of motion unless an external force acts on it

Law of Inertia

The greater the inertia, the harder it is to _______________

change the state of motion of the body

Law of Inertia defines this as the condition where there is no change in state of motion of a body.

Equilibrium

occurs when an object is completely at rest with balanced forces,

Static Equilibrium

occurs when an object moves at constant velocity with forces still balanced.

Dynamic Equilibrium

"Force is equal to the rate of change of momentum.”

Law of Acceleration

refers to the motion of an object traveling at a constant speed along a circular path.

Uniform Circular Motion

It is always directed toward the center of the circle and is responsible for changing the direction of velocity.

Centripetal Acceleration

This keeps the object moving in the circle

Centripetal Force

states that for every action, there is an equal and opposite reaction, meaning forces always occur in pairs between interacting objects

Law of Interaction

Newton's Third Law of Motion, explains that whenever one object exerts a force on a second object, the second object exerts a force of equal magnitude but in ________ direction on the first

opposite
