Inertia

• the tendency of an object to resist a change

  in motion unless an outside force acts on the object.

• Objects change their state of motion only when a

  net force is applied.

• Net force is equal to mass times acceleration.

Weight

• a measure of the gravitational force exerted on

  an object

• Net force is equal to mass times acceleration.

  The unbalanced force on an object determines

  how much an object speeds up or slows down.

• quantity defined as the product of the

  mass and velocity of an object

Newton's first law

• quantity defined as the product of the

  mass and velocity of an object

• gives the size of the

  gravitational force between two objects.

• Objects change their state of motion only when a

  net force is applied.

Newton's second law

• Objects change their state of motion only when a

  net force is applied.

• When one object exerts a force on a second

  object, the second object exerts a force equal in

  size and opposite in direction on the first object.

• Net force is equal to mass times acceleration.

Newton's third law

• When one object exerts a force on a second

  object, the second object exerts a force equal in

  size and opposite in direction on the first object.

• the motion of a body when only the force of

  gravity is acting on the body

• the

  constant velocity of a falling

  object when the force of air

  resistance is equal in

  magnitude and opposite in

  direction to the force of gravity.

Law of universal gravitational

• the curved path that an object follows

  when thrown, launched, or otherwise projected near the

  surface of Earth.

• quantity defined as the product of the

  mass and velocity of an object.

• gives the size of the

  gravitational force between two objects.

Momentum

• quantity defined as the product of the

  mass and velocity of an object

• the motion of a body when only the force of

  gravity is acting on the body

• the

  constant velocity of a falling

  object when the force of air

  resistance is equal in

  magnitude and opposite in

  direction to the force of gravity

Projectile motion

• the motion of a body when only the force of

  gravity is acting on the body

• the curved path that an object follows

  when thrown, launched, or otherwise projected near the

  surface of Earth

• a measure of the gravitational force exerted on

  an object

Terminal velocity

• the

  constant velocity of a falling

  object when the force of air

  resistance is equal in

  magnitude and opposite in

  direction to the force of gravity.

• gives the size of the

  gravitational force between two objects.

• Net force is equal to mass times acceleration.

Freefall or Freefall-motion

• the tendency of an object to resist a change

  in motion unless an outside force acts on the object

• the motion of a body when only the force of

  gravity is acting on the body

• the

  constant velocity of a falling

  object when the force of air

  resistance is equal in

  magnitude and opposite in

  direction to the force of gravity
