speed
mass
force
friction
Which one has the LEAST inertia?
Inertia refers to ___________
(select all the apply)
the tendency of moving objects to remain in motion
the force which keeps moving objects in motion with a constant velocity
the force that keeps stationary objects at rest
the tendency of stationary objects to remain at rest
A skateboard rolls down a hill, reaches the level surface and eventually comes to a stop. The fact that the skateboard ultimately stops is best explained by ________.
the skateboard needs an additional unbalanced force to continue its motion
the presence of an unbalanced force can cause a moving object to stop
the presence of inertia causes it to stop
the natural tendency of any object is to stop at some point
Which has the MOST inertia?
Who would cause more damage when leaping over a small building?
Which of these has the MOST inertia?
Diagram 3 shows a cat chasing a rat. The inertia of the cat is bigger than the rat because.
The size of the cat is bigger than the rat
The length of the cat is more than the rat
The mass of the cat is bigger than the rat
Which of the objects listed below have the greatest inertia?
A 500 kg object that is not moving.
A 300 kg object that is not moving on the Moon.
A 250 kg object moving at 25 m/s.
A 700 kg object moving at 3 m/s.
Which explains why the tablecloth trick works?
The dishes are stuck in place due to air resistance.
The tablecloth is an ilusion.
The dishes have inertia, and therefore stay on the table.
magic
Which action increases the inertia?
Use a rougher card /
Use a smooth card /
Pull the card with greater force /
Change the coin to a heavier coin /
To calculate a
a = Force × m
a = Force ÷ m
a = Force + m
a = m ÷ Force
To calculate m
m = Force × a
m = Force ÷ a
m = Force + a
m = a ÷ Force
To calculate Force
Force = m x a
Force = m ÷ a
Force = a ÷ m
Force = m + a
The more massive an object is...
the harder it will be to get moving.
The harder it will be to stop.
the harder it will be to speed up.
all of the above.
What is the net force?
65 N left
65 N right
35 N left
35 N right
