2) What happens when you put a positive charge near the hockey puck? The positively charged puck repels away from the positive charge. When the mass is changed to
a heavier mass the puck moves a lot slower
and when it is changed to a lighter mass the puck moves quicker.
What happens when you put a negative charge near the hockey puck?
What do you think would happen if you placed two negative charges next to each other? Answer:
The charges would move away from each other
.
What is the acceleration of the puck?
If a constant force F is applied for a short time T, and if the puck has mass m and is initially at rest, then the puck will accelerate to a speed v given by v = aT where
a = F/m
is the acceleration of the puck. … Given that the acceleration to to gravity is 9.8 m/s
2
, the acceleration of a puck is huge by comparison.
What forces are acting on the hockey puck?
For example, if I take a slap shot on a hockey puck, from what I understand, the forces acting on the puck are
friction, the normal force, and the puck’s weight
.
What causes a hockey puck to stop?
Friction
is the loss of kinetic energy into thermal energy, which is why the block slows down. So let’s think about this—can you relate this to hockey? The players each have a hockey stick and they want to hit the puck into the goal.
Why does the puck slow down after being hit?
Although it is slick, an ice surface provides some friction that slows the puck. … An object sliding across a table or floor slows down
due to the net force of friction acting on the object
.
How hard does a hockey puck hit?
During a hockey game, a puck can reach the speeds
of 100 miles per hour
(160 km/h) or more when struck.
What do the direction and strength of field lines indicate for the (+ charged puck?
The direction and strength of the field lines in this simulation represent
where the puck will travel
. … The closer the proton is to the puck, the farther the puck will travel. If a electron is put near the puck, the arrow will point towards the electron because the puck and electrons attract.
What do you notice about the direction of the arrows as you move the charge around the puck?
The arrows still show the direction of the puck and similar charges still
repel
and opposite charges still attract.
What do the E field sensors show?
1) The E-field sensors show
an arrow
, which means they’re measuring a vector quantity. The applet also reports the magnitude and direction of the red arrow. … Putting all of this information together, the E-field sensor measures a vector related to the potential gradient.
What law of motion is hockey?
According to
Newton’s First Law
, the hockey player will continue to move in that direction and speed until acted upon by another force.
Does gravity do work on a hockey puck sliding across the ice?
The normal force acts on the hockey puck as it slides across the ice.
Zero
; the normal force is (by definition) perpendicular to the motion, so there is no work done. … Positive; gravity pulls down, and the puck falls down. They are in the same direction, so positive work.
What type of friction is used in ice hockey?
For example, friction slows a hockey puck sliding on ice. But when objects are stationary,
static friction
can act between them; the static friction is usually greater than the kinetic friction between the objects.
What does dump the puck mean?
The Dump and Chase in ice hockey is
when the puck-possessing team crosses the red line and dumps the puck deep into the opposing teams’ zone
. Doing so will allow your speedy wingers to chase down the puck and catch opposing defensemen off-guard.
Which force keeps an ice hockey puck from sliding forever?
No net force means no movement, so you apply
a pushing force
, such as a hit from a hockey stick, which results in the puck travelling at a constant speed forever.
