Action: Cannon rolling back. Reaction: Ball being launched forward
Action: Ball being launched forward. Reaction: Cannon rolling back
Action: Cannon rolling forward. Reaction: Ball falling back

Two large rocks, a 1,000 kg rock and a 500 kg rock, are rolling downhill. According to Newton's 1st Law, which rock has more inertia?
The 1,000 kg rock
The 500 kg rock
They have the same amount of inertia
There's not enough information to answer this question
After bringing a scale to the moon, the astronaut discovers they have a lower weight than they do on Earth. Why is this the case?
Because gravity is higher on the moon
Because the moon is larger than the Earth
Because gravity is lower on the moon
The scale is broken; your weight is the same everywhere
True or False: Your mass is the same on the moon as it is on Earth
True
False
Determine the net force of the FBD in the picture shown above.
Newton's First Law States:
F = ma
For every action, there is an equal and opposite reation.
An object at rest remains at rest, unless acted upon by a net force. An object in motion remains in motion, unless acted upon by a net force.
Newton's Second Law States:
F = ma
For every action, there is an equal and opposite reation.
An object at rest remains at rest, unless acted upon by a net force. An object in motion remains in motion, unless acted upon by a net force.
Newton's Third Law States:
F = ma
For every action, there is an equal and opposite reation.
An object at rest remains at rest, unless acted upon by a net force. An object in motion remains in motion, unless acted upon by a net force.
What is a force?
A push or pull that acts on an object
A mythical power in Star Wars
The mass of an object
The movement of an object
A net force will cause an object to:
Gain more mass
Accelerate in the opposite direction as the net force
Remain still
Accelerate in the same direction as the net force
A balanced force can result in: (Check all that apply)
An object remaining still
An object gaining speed
An object gaining mass
An object moving at a constant speed
Inertia is entirely based on an object's:
Speed
Size
Mass
Volume
What is the relationship between the force the cannon puts on the ball and the force the ball puts back on the cannon?
The force on the ball is greater
The force on the cannon is greater
The forces are equal
The forces are unequal, but it's impossible to say which way
When a kangaroo jumps, the kangaroo applies an action force on the ground. The reaction force: (Check all that apply)
Is greater than the action force
Is equal to the action force
Cancels out the action force
Is exerted by the ground
Acts on the kangaroo
What unit is used to measure force?
Newtons (N)
Kilograms (kg)
Meters (m)
Pounds (lbs)
A biker travels at constant velocity. All of the following are true except:
The force of friction acts opposite the direction of his motion.
The force of friction is equal to the forward force he applies.
He has a net force acting on him.
The normal force is equal to his weight.
What's the net force on the object shown above?
