Section 1

(25 cards)

velocity

Front

Speed in a given direction

Back

inertia

Front

(physics) the tendency of a body to maintain is state of rest or uniform motion unless acted upon by an external force

Back

Friction

Front

A force that opposes motion between two surfaces that are in contact

Back

acceleration

Front

Change in velocity divided by the time it takes for the change to occur

Back

unbalanced force

Front

Forces that produce a nonzero net force, which changes an object's motion

Back

Gravity

Front

A force of attraction between objects that is due to their masses.

Back

Newton's Third Law of Motion

Front

for every action there is an equal and opposite reaction

Back

speed

Front

Distance travelled per unit time

Back

Mass

Front

the amount of matter in an object

Back

Acceleration

Front

increase in speed

Back

Weight

Front

the force of gravity on an object pulling it down

Back

Newton's Second Law of Motion

Front

"Acceleration depends on the object's mass and the net-force acting on it."

Back

Force

Front

A push, pull, or twist.

Back

time graph

Front

Straight line =constant speed, steeper line = faster

Back

balanced force

Front

Equal forces acting on an object in opposite directions

Back

Terminal Velocity

Front

The point at which a falling body ceases to accelerate but fall at a constant speed because it's weight is balanced by air.

Back

3rd law

Front

For every action there is an equal and opposite reaction

Back

net force

Front

The combination of all forces acting on an object

Back

average speed

Front

The overall rate of speed at which an object moves; calculated by dividing the total distance an object travels by the total time.

Back

gravity

Front

A force of attraction between objects that is due to their masses.

Back

direction

Front

Form of natural selection in which the entire curve moves; occurs when individuals at one end of a distribution curve have higher fitness than individuals in the middle or at the other end of the curve

Back

Inertia

Front

tendency of an object to resist any change in an it's motion.

Back

2nd law

Front

Force = mass x acceleration

Back

motion

Front

An object's change in position relative to a reference point.

Back

1st law

Front

(Law of Inertia) an object in motion tends to stay in motion & an object at rest stays at rest unless acted upon by an outside force.
