1
A cart with an initial velocity of 2 m/s with no fans (no force) on it will have an ending velocity of
0 m/s
1 m/s
2 m/s
4 m/s
2
Fan Cart Physics Gizmo demonstrated Newton's
3rd Law
(every action has an
equal
and
opposite
reaction) by showing...
the cart with no fans stayed the same speed
the cart increased its speed with more force
the cart with fans in opposite directions stayed the same speed
the fans blew left and the cart went right
3
Newton's
1st Law
of
Inertia
was demonstrated when
the cart with no fans stayed the same speed
the cart with two fans in opposite directions stayed the same speed
acceleration of the cart was 0 m/s
all of the above
4
When you triple (x3) the
force
on the cart, the acceleration
stays the same
is doubled (x2)
is tripled (x3)
is cut by a third (x1/3)
5
The cart reaches a velocity of 4.8 m/s in 2 seconds. What is its acceleration?
9.6 m/s^2
2.4 m/s^2
4.8 m/s^2
0 m/s^2
6
If you apply a constant force to a cart, it will keep a constant velocity (stay at the same speed)
False
True
7
When you double (x2) the
mass
of the cart, the acceleration
is cut in half (x 1/2)
stays the same
is tripled (x3)
is doubled (x2)
8
Newton's
2nd Law
states that F=ma or a=F/m
True
False
9
During Fall Break, I will demonstrate Newton's Laws of Motion by
Who cares I just am looking forward to having no school for a week.
Giving up on moving objects in my home because it requires too much force
Using more force to move heavy objects in my home
Resting in one place and not moving
10
When one fan was blowing and creating a force on the cart, the velocity of the cart
stayed the same
decreased
was 0 m/s
increased
11
Fan Cart Physics Gizmo demonstrates
Newton's 2nd Law
by showing
doubling the mass on the cart cuts the acceleration in half
all of the above
force and acceleration are proportional to each other
doubling the force on the cart doubles the acceleration
