What is the definition of force?

• A push or pull action on an object

• The amount of matter in an object

• The distance covered over time

• The rate of change of speed

Which force is NOT mentioned as acting on a long jumper?

• Muscular force

• Air resistance

• Magnetic force

• Gravity

How does air resistance affect a sprinter?

• It speeds them up

• It pulls them downwards

• It opposes their motion

• It has no effect

What is the role of friction in cycling?

• It has no effect

• It increases speed

• It helps the bike stick to the road

• It reduces air resistance

What is the formula to calculate force?

• Force = Mass - Acceleration

• Force = Mass x Acceleration

• Force = Mass / Acceleration

• Force = Mass + Acceleration

Which force is responsible for keeping a bicycle in contact with the road?

• Magnetic force

• Air resistance

• Gravity

• Muscular force

What effect does muscular force have on a cyclist?

• It slows them down

• It helps them maintain balance

• It allows them to accelerate

• It reduces air resistance
