Newton’s 1st law
Newton’s 2nd law
Newton’s 3rd law
Law of Gravity
Words of Motion F J
An object will be harder to move if
it has more of this.
2
What is mass.(or matter)
3
A moving object tends to stay in
motion unless this acts on.
4
What is an unbalanced
force?5
This is the kind of forces acting on a book not moving
on a desk.
6
What are balanced forces?
7
This force slows down many
objects on earth.
8
What is friction?
9
Newton’s 1st law can be summed up in this one
word. 10
What is inertia?
11
This will happen to an object that
has a force applied to it.
12
What is accelerate?
13
If you increase the force on a moving
object this will happen to the acceleration.
14
What isit will increase?
15
If you increase the mass of an object, this will happen to the acceleration.
16
What isit will decrease?
17
These 2 things determine the acceleration of
any object. 18
What are mass and force?
19
This equation explains the
relationship between force, mass, and
acceleration.20
What is F = m X a ?
(Or any member of the fact family.)
21
22
If you throw a heavy ball while you are wearing skates, this will
probably happen.
23
What is you’ll be pushed back
by the ball?
24
Every action has an equal and opposite
one of these.
25
What is reaction?
26
When a balloon flies across a
room because of air pressure, the
push of air is this.
What is the action?
27
28
When the thrust of a rocket pushes it into space, the moving
rocket is this.
29
What is the reaction?
30
This is the reaction when rowers use their oars to push
water.
What is the boat moves forward?
31
A feather will fall more slowly
than a rock because of this.
32
What is air resistance?
33
34
This scientist found that without air
resistance, heavy and light objects fall at
the same rate.
Who is Galileo?
35
As an object falls, it’s velocity does
this.
36
What is it increases?
(or accelerates.)
37
Objects close to earth accelerate at this rate as they
fall.38
What is 9.8 m/s2?(meters per second, each second)
39
The moon stays in orbit because of these two forces.
40
What are gravity and
inertia?41
Objects with mass pull each other because of this.
42
What is gravity?
43
How fast an object changes
position.
44
What is speed?
45
The speed and direction of a
moving object.
46
What is velocity?
47
A push or a pull that can be either
balanced or unbalanced.
48
What is a force?
49
It measures how much gravity
pulls an object.
50
What is weight?
51
Final Jeopardy
52
FINAL JEOPARDY
This ancient scientist thought heavy objects fall faster than light
ones.53
Who is Aristotle?
