Question Answer
MotionMovement of an object
MotionChange in position
ForceObject interactions with it's environment
DynamicsStudy in which force produces motion
ForcePush or pull
Net forcePhysical quantity that is capable of change an object's state of motion
Net forceVector sun of all forces acting on a body
Contact forceresult from physical contact with object involved hand, feet, etc
Non contact forceaction at a distance forces
Law of inertia A body at rest remains at rest and a body at motion remains at motion with a constant velocity in the absence of an unbalanced applied force
Law of accelerationAcceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the mass of an object
Law of interactionWhen an object exerts a force on another object, the second object on the first force of the same
Projectile motionObject thrown with an initial horizontal velocity and acted upon by the Earth's pull of gravity
TrajectoryProjectile that travels in a curved path
Curved path of a projectilecombination of horizontal and vertical motion
Horizontal componentignored effect of friction
Curved path of projectileCombination of horizontal & vertical component
ParabolaAccelerates only in vertical direction while moving at a constant horizontal velocity
Workis the measurement of energy pass, occurs when annobject is moved by external force, atleast applied in direction
EnergyAbility to do work
