1.Frame of reference – the objects used
to compare an object’s position to its
surroundings.

What I Know
Position = location (where you are)
Something that is constantly changing position is in
MOTION.
How can I find the speed of an object?
Distance (object moves)
______divided by _______
time (spent moving)
70 miles / 1 hour = 70 miles per hour
= Speed
What I Know
Examples :
60 km in 1 hour = speed is 60 km per hour
90 m in 1 sec. = speed is 90 m per second
120 miles in 2 hours = speed is 60 miles per hour
120 km in 3 hours = speed is 40 km per hour
Velocity = speed + direction
Ex: North at 120 miles per hour
Forces can be big or small

Forces can cause an object to start or stop
moving.
Forces can also change the speed or direction
of a moving object.
An example of acceleration is
____________________
Friction acts between two objects that touch.
An example of friction is ______________
Friction causes objects in motion to slow down
or stop.
The greater the mass of an object, the stronger
the pull of gravity.
