1
Describe Newton's Second Law
tells us how mass and force affect acceleration. F=ma
motion stays in motion, object at rest will stays at rest
action/reaction
none of these
2
Which formula do we use for Newton's 2nd Law?
F = m/a
F = m - a
F = m + a
F = m x a
3
What is the unit for force?
kg (kilogram)
m (meter)
m/s2
N (newton)
4
An object collides with a wall and rebounds, this is an example of which of Newtons Law?
Law of Acceleration
Law of Inertia
Law of Action-Reaction
Law of the Universe
5
What is the formula for weight?
Fw = m/g
Fw = m x F
Fw = m x g
none of these
6
For a given force the more mass you have,
the more acceleration you get
the less acceleration you get
7
What is Newton's first law of motion also called?
law of action-reaction
law of inertia
first law of acceleration
law of newton
8
What is the weight on Earth for a 100 kg object? (g= 10 m/s
2
)
1000 m/s2
1000 N
10 N down
10.0 m/s2
9
The bigger the force acting on an object...
the smaller the acceleration
the greater the acceleration
10
Who is creditied with the three laws of motion?
Tycho Brahae
Aristotle
Isaac Newton
Galileo
11
Unit of mass?
m
N
none of these
g, kg, lbs

3x108
13
If there are no forces acting on a rock moving in space, its velocity is...
changed
3x108
-10m/s2
constant
14

2
?
2.0 N
5.0 N
0.50 N
50 N
