Section 1

(28 cards)

The greater the force....

Front

the more the acceleration.

Back

m/s/s

Front

units for acceleration

Back

What do you do to find the net force if the forces are in the opposite direction?

Front

subtract the forces

Back

Mass

Front

The quantity of matter in an object. A dictionary has a mass of about one kilogram

Back

velocity

Front

speed in a certain direction

Back

What do you do the find the net force if the forces are in the same direction?

Front

add the forces

Back

m/s

Front

units for speed

Back

m

Front

units for distance

Back

The greater the mass.....

Front

the more force is needed to accelerate.

Back

Weight

Front

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity. It is measured in newtons. You may weigh 100 pounds on Earth but in space your weight will be reduced.

Back

Volume

Front

The quantity of space an object occupies.A bowling ball and basketball are about the same size and take up the same amount of space, therefore they have the same, or similar, volume

Back

Force

Front

A push or a pull, measured in newtons. Pushing a desk across the room.

Back

Newton's 1st law

Front

an object at rest will stay at rest and an object in motion will stay in motion until acted upon by an unbalanced force. Also known as the law of inertia

Back

What is needed to determine speed?

Front

distance and tim

Back

m/s north

Front

unit for velocity

Back

Newton

Front

(Symbol: N) is the International System of Units (SI) derived unit of force. .

Back

unbalanced forces

Front

when the net force does not equal 0 Newtons

Back

Newton's 3rd law

Front

for every action there is an equal and opposite reaction. Also known as the law of action-reaction

Back

Newton's 2nd law

Front

Force = mass x acceleration

Back

speed

Front

distance in a certain amount of time s=d/t

Back

What is needed to determine velocity?

Front

distance, time, and direction

Back

net force

Front

sum of all the forces

Back

Inertia

Front

The property of things to resist changes in motion.

Back

The smaller the mass...

Front

the less force is needed to accelerate it.

Back

Friction

Front

Contact force between objects that slide (or tend to slide) against each other.

Back

The smaller the force.....

Front

the less the acceleration.

Back

acceleration

Front

a change in velocity

Back

balanced forces

Front

when the net force is 0 Newtons

Back
