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.
