my nephew is running in the cyo prelims today. i am curious how much time difference a composite track will add to his time. i am not interested in Olympics. he is 8th grade Track and Field.
The dark surfaces heat up faster because dark surfaces attract sunlight faster than light surfaces.
i ran a 24.7 200 in state and got 4th so.. and if you run under a 12 in the 100 meter dash that's pretty good, i run a 12 flat.
Faster: Surfaces with less friction (smooth) ;slanted surfaces Slower: Surfaces with more friction (sticky surfaces, rough surfaces), uphill surfaces Of course a slanted surface with too much friction will also make the car slower.
Land surfaces warm faster and cool faster
Yes, as will fast walking and swimming, etc. Though, running on hard surfaces, while wearing unsuitable footwear, may eventually cause damage to ankle and leg joints

Friction
Land surfaces heat up and cool down faster than water surfaces.
surfaces that are rough provide more friction that can make athletes run faster
Snails move faster on rough objects as the sticky liquid they use for locomotion gets good friction and helps it to move. But on rough surfaces, the frictional force is much less and the snail can hardly move.
Different texture
It moves faster and rises
