Details
A push or a pull.
Force
Forces can make things move that were already standing still
true
What happens when two people push on a chair in the SAME direction?
the chair will move in the direction they are pushing pretty fast because there are two forces acting on it
Which state of matter do the particles move the fastest?
Gas
It begins to move
Arrows
Larger forces are represented using smaller arrows.
false. The size of the arrow represents the size, or magnitude of the force.
Applying only 1 force to an object will cause it to move.
true. 1 force is an unbalanced force
In which state of matter do the particles merely vibrate?
Solid
What happens when a ping pong ball is rolling towards you and you apply a force to it?
It will slow down
This opposing force slows all moving objects down
friction
Forces are only seen in sports.
false. Forces are found everywhere!
What do you have to do to stop something from moving? (include direction)
Apply or exert a force in the opposite direction the object is moving
When ice turns to liquid water, that process, or change in the state, is called...
Melting
What happens when a ping pong ball is rolling away from you and you apply a force to it?
It moves faster
Two equal forces acting on an object in opposite directions
Balanced Forces
Applying only 1 force to an object will cause it to move.
true. 1 force is an unbalanced force
Two equal forces acting on an object in opposite directions
Balanced force
What happens to particles if they are flying all around the container, and the temperature is lowered?
they slow down/they lose energy
What happens when a ping pong ball is rolling past you, from your right side to your left side and you apply a force to it?
It will change directions
The sum of all the forces acting on an object, or the total force
Net force
Apply a force in the opposite direction an object is moving will cause it to slow down.
true
What do you have to do to get an object to move faster? (don't forget to include direction)
Apply or exert a force in the same direction the object is moving.
When water vapor turns to liquid water, that is called...
condensation/condense
What happens when a friend comes over and applies a force on the ping pong ball from the other side of the table? (assume the forces are the same)
