Bob hits a hockey puck with his stick. What forces are acting on the puck DURING THE ACTUAL HIT?
a = weight
b = friction
c = tension
d = forward force
e = normal force
Write down every letter that applies (in order) and without using any commas.

Correct! The forces acting on the hockey puck during the actual hit are:
a) Weight: The force due to gravity acting vertically downwards.
e) Normal force: The force exerted by the surface on the puck, acting perpendicular (normal) to the surface.
d) Forward force: The force exerted by Bob's stick on the puck in the forward direction.
b) Friction: The force opposing the motion of the puck, acting opposite to the forward force.
Great job! To determine the forces acting on the hockey puck during the actual hit, we can break it down as follows:
a) Weight (a): The force of gravity acting on the puck is always present, regardless of the situation.
b) Friction (b): As Bob hits the puck with his stick, there will be a force opposing the motion due to friction. This force is present between the puck and the surface it is on.
c) Tension (c): Tension is the force transmitted through a string, rope, or any similar medium. As mentioned, we're focusing on the forces during the actual hit, so tension doesn't come into play in this scenario.
d) Forward force (d): When Bob hits the puck with his stick, he applies a forward force to the puck. This force is responsible for initiating and accelerating the puck's movement forward.
e) Normal force (e): The normal force is the support force exerted by a surface, perpendicular to the contact surface. During the actual hit, the normal force is present but doesn't directly influence the puck's movement.
Therefore, based on your analysis, the correct answer is aedb, which includes the forces a, e, d, and b.
