• mass of skater
• shape of the track
• surface of the track 

Which would NOT change the potential energy of the skater? 

• putting the skater higher up on the track
• increasing the friction
• making the track steeper and further from the ground
• moving the starting point of the skater

Which statement is true about a skater on a U shaped track? 

• speed remains constant from one end to the other
• speed starts high at the top and reduces as the skater reaches the bottom of the track
• speed increases as they move down the track and then decreases as they move up the other side 
• speed is zero the entire time
