STEM Olympics: Forces for Downhill Skier

What is the main force that skiers use to start their race?

• Gravity

• Friction

• Push off the snow

• Wind resistance

According to Newton's Second Law of Motion, what causes an object to accelerate?

• Balanced force

• Unbalanced force

• Gravity

• Friction

What role does gravity play in downhill skiing?

• It slows the skier down

• It pulls the skier to the side

• It pulls the skier down the slope

• It stops the skier

What is the effect of friction on a skier?

• It speeds up the skier

• It slows down the skier

• It makes the skier jump higher

• It helps the skier turn

How can skiers minimize wind resistance?

• By standing upright

• By tucking in their arms

• By wearing loose clothing

• By jumping higher

What is the term for turning skis on their edge to go around turns?

• Sliding

• Edging

• Gliding

• Skidding

What happens when a skier keeps their skis flat?

• It decreases speed

• It increases speed

• It causes more friction

• It makes turning easier

What force attracts objects down to the surface of the Earth?

• Friction

• Wind resistance

• Gravity

• Push off the snow

What is the main challenge for skiers when going over jumps?

• Increasing speed

• Reducing wind resistance

• Staying close to the surface

• Turning quickly

What happens to a skier when they are in the air for a long time?

• They speed up

• They slow down

• They turn more easily

• They reduce friction
