velocity
speed in any direction
what is velocity?
a force between an object and the surface it is moving over
what is friction?
the amount of matter that makes up and object
what is mass?
the moment when two objects hit each other
what is collision?
a push or pull that can change the motion of an object
what is force?
by friction or if a force in the opposite direction is applied
how can objects slow down?
the object will slow down
what happens when a surface has friction?
it requires more force
if an object has more mass, does it require more or less force to move it?
they bounce off and move in the opposite direction
what happens to the objects when they collide?
the object will move the opposite direction
what happens when a force that is too strong is applied in the opposite direction of an already moving object?
by exerting a force in the same direction the object is going
how can objects speed up?
rough surfaces
what kind of surfaces have more friction?
if an object has less mass, does it require more or less force?
they will bounce off and have an equal change in motion
what happens if two objects of the same mass collide?
stronger forces will push or pull stronger, which then creates a bigger change in velocity or motion of an object
how does a stronger force make a greater change in velocity or motion of an object?
start moving, stop moving, slow down, speed up, go in the opposite direction
what are different ways an object's velocity changes?
the object will move more and slow down slower
what happens if there is no friction?
the less massive an object is, the bigger change in motion happens
what is the relationship between the mass of an object and its change in motion?
the object with less mass will have a bigger change in motion
what happens if two objects of a different mass collide?
f=m*a
what is the formula to finding force?
