Forces Flashcards
Force
a push or pull one body exerts on another
Newton’s first law
an object moving at a constant velocity keeps moving at that velocity. an object at rest stays at rest unless acted upon by a net force.
Inertia
the tendency of an object to resist any change in motion
Net Force
combination of all forces that act upon an object
Gravity
every object will exerts a force on every other objects. this force is gravity. this force is felt as a pull.
Mass
the amount of matter of stuff object has measured in kilograms.
Weight
the measure of force of gravity on an objects mass. how hard your pulled toward earth.
Newton’s second law
the net force acting on an object causes the object to accelerate in relation to the size of the force and mass of the mass of the object.
Friction
is a force that opposes motion between two surfaces that are touching each other.
Static friction
friction that resists getting an object moving.
kinetic friction
friction that resists keeping an object moving.
Newton’s third law
to every action there is an equal and opposite reaction force
Projectile
anything flown or shoot through the air.
centripetal force
forces acting toward the center of a curved or circular path.
momentum
the force required to stop.
