The Need for Speed
Speed with direction
Velocity
Forces that require contact between two objects or substances.
A push or pull.
Force
For every action there is a reaction.
Newton's 3rd Law
When air creates friction against a falling object.
Air Resistance
The rate at which an object moves. It's equation is distance/time.
Speed
Forces that do not require contact.
Non-Contact Forces
If a man pushes an object with 300N of force and the object resists with 100N of force, this is the net force.
200N
The tendency of an object to resist a change in its movement aka laziness.
Inertia
The force that continuously pulls an object in a circular path.
Centripetal Force
The rate of change in velocity.
Acceleration
The force that results from pushing or squeezing an object.
Compressional Force
The splitting of a nucleus of an atom.
Nuclear Fission
A body or object remains at rest unless acted upon by an unbalanced force.
Newton's 1st Law
The force that causes objects that are dropped to accelerate toward Earth.
Gravity
If you travel 150km in 4 hours, this is your average speed.
37.5km per hour
A pull exerted on an object such as during a game of tug-of-war.
Tensional Force
This typeof force is the upward force exerted on objects in a fluid.
Buoyancy
The net force applied to an object = it's mass x acceleration.
The curved path an object follows when it is thrown.
Projectile Motion
The force that resists motion in two objects.
Friction
All forces added together.
Net Force
Mass cannot be created or destroyed.
Law of conservation of mass
The property of a moving object that can be expressed as mass x velocity.
Momentum
The constant velocity after which an object stops accelerating.
Terminal Velocity
