Force and Motion Anchor Project

Motion

• Motion is change in an object's position

Newton's First Law

• An object at rest will remain at rest while an object in motion will stay in motion unless it is acted on by an unbalanced force

Newton's Second Law

• THe acceleration of an object equals the net force acting on the object divided by the object's mass.
• This can be represented by the equation: A=F/m

Newton's Third Law

• For every action there is an equal and opposite reaction

Frame of Reference

• Something that is not moving respect to an observer that can be used to detect motion

Distance

• The length between two points

Direction

• A course along which someone or something moves

Vector

• A measurement that has both size and magnitude, and direction of the motion

Speed

• How fast or slow something moves
• Speed can be represented by the equation: S=d/t

Average vs. Instantaneous Speed

• Average speed -- Taking the overall distance divided by the amount of travel time
• Instantaneous speed -- The speed of an object at any time

Velocity

• The measurement of both speed and distance
• Velocity can be represented by the equation: s+d=V

Acceleration

• The measure of the change in velocity of a moving object

Force

• Push or pull on an object

Force and Motion

• Forces cause all motion

Net Force

• The overall force acting on an object that takes into account all of the individual force acting on the object

Unbalanced vs. Balanced Forces

• Unbalanced forces cause a change in an object's motion
• Balanced forces are opposing forces that are equal in push or pull

Electric Charge

• An electric charge is a physical property of particles or objects that causes them to attract or repel each other without touching

Electric Force

• The attraction or repulsion between two charged particles

Magnetic Force

• The force a magnet exerts on certain materials or other magnets

Gravitational Force

• Gravity is a force of attration between objects that have ass or energy

Frictional Force

• A force that opposes motion between any surfaces that are touching
