2. 1. Friction occurs with the movement of two objects in _____________ with each other.
2. Friction is a force that is in the ______________ direction of travel.
3. Static friction occurs when two objects are in contact and ___________ moving.
Kinetic friction occurs when
two objects are in contact and
____________ against
each other.
contact
opposite
not
moving

3. heat
5. Friction always causes ______________ and ________________ of surfaces.
6. When an object is falling through the air and the drag (resistance) equals the pull of
gravity, ____________ ____________ has been reached.
wearing
terminal velocity

4. 7. What is Newton’s first law?
An object at rest or in uniform motion will stay at rest or in uniform motion until a net force is applied.
In simple terms: The motion of an object will not change unless a force is applied

6. 8. What is meant by a “net force”?
The overall force on an object when all the individual forces acting on an object are added together.
If 15 Newtons of force are applied to the right and 20 Newtons of force are applied to the left, the net force will be 5 Newtons to the left
15N
20N
net of 5N to the left

7. 9. What is meant by a balanced force?
When forces in opposite directions are equal
10N
10N
(think of a balanced see-saw…
which is a bunch of unbalanced
forces balancing each other!) E R R E

8. 10. The more force you apply to an object, the greater it will _____________________.
11. An unbalanced force will cause
_______________, _______________,
or______________________________.
The more an object’s mass, the
greater the ___________________
will have to be to make it
_________________ (speed up).
accelerate (speed up)
acceleration
deceleration
change in direction (vector)
force applied
accelerate
