A skater needs to have good balance on the ice in order to remain stable. This is due to the understanding of the center of mass, which is the point of balance where all the mass of the object is concentrated. As the figure skater is not symmetric object, the center of mass is in the hips and the position is unstable. Therefore, to maintain the balance, a figure skater needs to keep the center of mass moveable, and directly above the point of support. Based on where the blades and the weight are, dancing pairs do complicated positions and lifts (Orr).
The skater applies pressure using the metal blades of the skates, and by doing that, the melting point of the ice reduces by a few degrees. This produces from two to three centimeters of slippery field …show more content…
According to The Physics Classroom, a projectile is when an object moves both vertically and horizontally and the gravity force is the only force that is acting upon it. The trajectory that the body draws in the air is a curved path called a parabola. When jumping from the ice, the skater accelerates his body and starts moving vertically, while the gravity is pulling downwards. The horizontal velocity is constant, but the vertical velocity is decreased by the gravity force. Therefore, when reaching the top of the parabola, the vertical velocity is equal to zero. When the man throws his partner in the air, she arrives at the same time and point as he does when she lands even though the two skaters are experiencing different types of velocity (Orr,
