Fundamentals Physics - Forces And Motion

Front 1

a "push" or "pull" that changes the way things move

Back 1

force

Front 2

True or False? You can see forces.

Back 2

false

Front 3

True or False? If false, explain why.
Balanced force do not cause a change in motion.

Back 3

true

Front 4

movement from place to place

Back 4

motion

Front 5

the force that pulls all materials together across space

Back 5

gravity

Front 6

Using your knowledge of balanced forces, explain why a table stays in one place

Back 6

The forces of gravity pulls the table down.
The table is pushed up by the ground or the floor that it stands on.

Front 7

the upward force on an object immersed in a liquid or a gas, enabling it to float or appear it become lighter

Back 7

buoyancy

Front 8

How does buoyancy explain why a ship that is overloaded with cargo may sink?

Back 8

The ship may sink if it becomes heavier than the water's buoyancy, or the upward force of the water.

Front 9

True or False? If false, explain why.
A balanced force has to be stationary.

Back 9

false
A moving object will continue going at a steady speed if the forces are balance.

Front 10

What do unbalanced forces do to a moving object traveling at a constant speed?

Back 10

Unbalanced forces may cause the moving the object to either speed up or slow down.

Front 11

The size of a force on an object depends on what two things?

Back 11

mass and acceleration

Front 12

the rate at which speed is changed

Back 12

acceleration

Front 13

the amount of matter in an object

Back 13

mass
