If you double the force of an object what happens to the acceleration?
The object explodes
It halves
It disappears
It doubles
2
What is the unit of force?
Joules
Ohms
Newtons
Meters
3
Net force is
When you add up the magnitude of all forces.
combination of all the forces acting on an object
The amount of force applied by a net.
The force that counteracts gravity.
4
What is Newton's first law of motion?
You can't have your pudding before you eat your meat.
Every action has an equal and opposite reaction.
an object will stay at motion/rest unless acted upon ...
F=ma
5

2
?
4 N
100 N
25 N
5 N
6
What is Newton's second law of motion?
F=ma
Every action has an equal and opposite reaction.
Objects require force to cause a change in motion.
You can't have your pudding before you eat your meat.
7
a force that opposes the motion of an object is
mass
friction
net force
inertia
8
the tendency of an object to resist a change in motion is
inertia
mass
acceleration
momentum
9
When you are moving at a high speed, inertia makes it hard to stop
false
true
10
The more inertia an object has...
the easier it is to move
The more acceleration it has.
The harder it is to move.
The less acceleration it has.
11
For every action, there is an equal and ___________ reaction.
opposite
equivalent
different
upwards
12
Force is
A push or pull.
An object's resistance to changing motion
The rate at which an object changes motion.
How much stuff is in an object.
13

14
momentum can be transferred from one object to another
False
True
15
Newton's first law of motion is also called
F=MA
action/reaction law
the law of inertia
law of gravity
16
overcoming an object's inertia always requires
unbalanced force
large mass
balanced forces
massive force
17
What is Newton's third law of motion?
You can't have your pudding before you eat your meat.
Every action has an equal and opposite reaction.
F=ma
Objects require force to cause a change in motion.
18
What is the reaction to punching the wall?
Nothing.
The wall hits you back with more force.
The wall hits you back, but with less force.
The wall hits you back with the same force.
19
momentum is directly related to
mass only
distance and mass
mass and velocity
velocity and distance
20
Acceleration is
How much stuff is in an object.
the measure of the change in velocity of a moving object
A push or pull.
An object's resistance to changing motion
