Phy. Sci. Vocab. 5&6

The vocabulary in Chapter 5 and 6.

Motion an object's change in position over time when compared with a reference point
Speed the rate at which an object moves; depends on the distance traveled and the time taken to travel that distance
Velocity the speed of an object in a particular direction
Acceleration the rate at which velocity changes; an object does this if its speed changes, if its direction changes, or if both its speed and direction change
Force a push or a pull; all have both size and direction
Newton the SI unit of force
Net Force the force that results from combining all the forces exerted on an object
Friction a force that opposes motion between two surfaces that are touching
Gravity a force of attraction between objects that is due to their masses
Weight a measure of the gravitational force exerted on an object, usually by the Earth
Mass the amount of matter that something is made of; its value does not change with the object's location
Terminal Velocity the constant velocity of a falling object when the size of the upward force of air resistance matches the size of the downward force of gravity
Free Fall the condition an object is in when gravity is the only force acting on it (think about the ride, Free Fall, at Six Flags)
Projectile Motion the curved path an object follows when thrown or propelled nar the surface of Earth
Inertia the tendency of all objects to resist any change in motion
Momentum a property of a moving object that depends on the object's mass and velocity
