news Flashcards
force
A push or pull exerted on an object in order to change the motion
motion
A change in position over time
Net force
The combination of all the forces acting on an object
speed
Distance traveled per rate of time
velocity
acceleration
acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object’s acceleration is given by the orientation of the net force acting
newtons first law
every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
Newtons second law
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
Newtons third law
His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.
Inertia
Dust comes out of the mat when beaten. Falling forward in transport when sudden breaks are applied. Leaves get detached from the tree when shaken hardly. Due to inertia, artificial satellites keep moving in a circular motion.
Friction
force that resists the sliding or rolling of one solid object over another.
mass
quantitative measure of inertia, a fundamental property of all matter.
