What upward force allows a high jumper to leave the ground?
What upward force allows a high jumper to leave the ground?
- The jumper pulls themselves up.
- Gravity provides a lift force.
- The ground accelerates the jumper upwards. (correct)
- Air pressure pushes the jumper up.
What does the interaction between a man and a football illustrate regarding forces?
What does the interaction between a man and a football illustrate regarding forces?
- Forces are one-sided during the interaction.
- The man and the football exert equal and opposite forces on each other. (correct)
- The football moves without exerting any force back.
- The man only affects the football's movement.
How does Newton's third law relate to a boy kicking a ball?
How does Newton's third law relate to a boy kicking a ball?
- The wall exerts an equal force back on the boy after the kick. (correct)
- The wall only absorbs the impact without reacting.
- The boy's foot remains still while the ball moves.
- The wall pushes the boy causing no effect on the ball.

Flashcards
Ground Reaction Force
Ground Reaction Force
The upward force exerted on an object, like a high jumper, by the ground as they push off.
Newton's Third Law
Newton's Third Law
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on another object, the second object exerts an equal and opposite force on the first.
Gravity
Gravity
The force that attracts objects with mass towards each other.

Study Notes
Newton's Third Law
- The ground pushes on the high jumper, causing the jumper to be propelled upwards
- Forces always come in pairs, according to Newton's third law
- For every action, there is an equal and opposite reaction
- The football and a man exert equal and opposite forces on each other, demonstrating Newton's third law
- The Earth and the moon exert gravitational forces on each other, exemplifying this law
- A boy kicking a ball against a wall exerts a force, the wall exerts an equal and opposite force, reflected in the ball's rebound.
