Transcript of Copy of Forces and Motion

Forces & Motion
Motion: The act of changing something's position or place.
1) When an object has moved, it has changed place.

2) It moves a distance from where it starts to where it ends up.
Velocity: Speed + Direction
Acceleration: The rate at which an object changes its velocity.
speeding up
slowing down
changing direction

Applied Force: When a force is APPLIED by a person or another object.
Frictional Force: A force that opposes the motion of two surfaces that are in contact with one another.
Air resistance
Normal Force: Exerted on a stable object in response to another object in contact with it. Works against gravity
Spring Force: A force that is exerted by a spring compression.
Gravitational: A force of mutual attraction that exists between all bodies of matter. Dependent on how much mass each body has, and how far apart they are from each other.
Non-Contact Forces
Contact Forces
Electrical: Force of attraction between unlike electrical charges +/-; Force of repulsion by alike electrical charges. +/+
Magnetic: The same as Electrical force, only while in motion
Frictional forces between the air and the surface of an object.
Any influence that causes an object, at rest, to move. It may also change the speed and/or direction of an object

The shortest distance between the starting point and the end point.
Tension: the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends.
