Is a hockey puck at equilibrium if it slides across the ice at a constant speed?
Yes, a hockey puck sliding across the ice at a constant speed is in equilibrium. The forces acting upon it are balanced, with no net force causing acceleration.
A hockey puck is sliding across a friction less surface what large force us needed?
No large force is needed for a hockey puck to slide across a frictionless surface. Once the puck is in motion, it will continue to move indefinitely without any additional force due to the absence of friction.
Can A hockey puck that slides across the ice at a constant speed be in equilibrium?
Yes, a hockey puck sliding across the ice at a constant speed can be considered to be in dynamic equilibrium. While the puck is moving, the forces acting on it are balanced, resulting in no acceleration in its velocity.
How is sliding friction shown in field hockey?
Sliding friction in field hockey is demonstrated when the player's feet slide on the ground as they change direction or come to a sudden stop. This friction helps players control their movements on the field by providing resistance against the sliding motion. The type of shoes worn by field hockey players, with studs or cleats, also play a role in enhancing sliding friction for better traction on the field.
Is it true that An air hockey puck bouncing off the sides of the table is an example of projectile motion.?
No, air hockey puck bouncing off the sides of the table is not an example of projectile motion. Projectile motion involves an object being launched into the air and following a curved path due to gravity, while the puck in air hockey is typically sliding along a flat surface.
