Question Answer
Sir Isaac Newton Seventeenth Century scientific genius who developed The Laws of Motion, Invented Calculus, the Reflecting Telescope,to name a few
Newtona??s First Law of Motion An object at rest will stay at rest unless acted upon by an unbalanced force. An object in motion will continue in motion with the same speed and in the same direction unless acted upon by an unbalanced force. (This Law is often called The Law of Inertia.
Inertia Term for resisting change of motion
Newtona??s Second Law of Motion Acceleration (change of speed and direction) (movement) is produced when a force acts on a mass. The greater the mass(of the object being accelerated) the greater the amount of force needed(to accelerate the object). This Law is often called F=M x A
Newtona??s Third Law of Motion For every action there is an equal and opposite reaction. This Law is often called a??Action-Reaction Forcesa??
Gravity The invisible force that pulls our mass and the mass of all objects towards the center of the earth. This pulling force is affected by distance.
Friction Friction is the resistance caused by any two objects in contact. It always acts in the opposite direction of the motion. This force attempts or stops objects from moving as well as turning kinetic energy into heat energy.
Force A push or a pull on an object that results in a transfer of kinetic energy.
Kinetic energy The energy of motion
Mass The amount of matter in an object.
Acceleration The rate at which velocity changes over time. ( change of speed and direction)
Speed The distance traveled in a certain amount of time; rate of momentum. Speed = distance/ Time S= D/T
Velocity The rate of motion in a particular direction before change
Momentum A property of a moving object, calculated by multiplying the objects mass by it velocity P=MV
Newton Metric unit of measurement for force. Named after you know who. (Can be measured with a spring scale)
Matter Anything that has mass and volume.
Volume The amount of space that matter takes up.
Density The amount of mass in a given volume of matter. Which means how tightly packed the particles in an object or thing.
Potential energy Stored energy in a non moving object, based on the objects position and condition (mass)
