Straight line motion
T/F :: In tug of war - the side with more people always wins
False - side with more force wins
speed
The distance an object travels per unit of time
If a force acts upon an stationary item , the object will
accelerate in the direction of force
In tug of war : if the rope doesn't move the forces are
balanced
In tug of war the rope always accelerates in
direction of greater force
Object will move in direction of more
force
If an object is changing direction
force is acting upon them
The tendency for an object to stay at rest and a tendency for an object in straight line motion to keep moving is
inertia
if a force stops acting on an object
keep going on at a constant speed
change in position
motion
An object in space not near anyone else will
move indefinitely
Which do you think will travel faster: a car that moves in a smooth, straight line or a car that veers back and forth and bumps against the sides of the track?
smooth straight line
The speed and direction of an object is
velocity
According to Newton's first law of motion , an object moving in a straightline at a constant speed
will continue moving the same way at the same speed until it is acted upon by an unbalanced forced.
