Question 1.
What is Newton's Third Law?
Show hintHide hint
Think about the relationship between actions and their responses.
Question 2.
Give an example of an action-reaction pair.
Show hintHide hint
Consider what happens when you exert force on another object.
3Question 3.
What does Newton's Third Law state?
- Action leads to motion.
- For every action, there is an equal and opposite reaction.
- Objects in motion stay in motion.
Show hintHide hint
Think of forces acting in pairs.
4Question 4.
True or False: When a ball is kicked, the force exerted by the foot is greater than the force exerted by the ball.
- True
- False
Show hintHide hint
Consider action and reaction relationships.
Question 5.
A skateboarder pushes off the ground to gain speed. If they weigh 60kg, calculate the force exerted by the skateboarder when they start moving with an acceleration of 2m/s².
Show hintHide hint
Apply Newton's Second Law to find the force.
Question 6.
An astronaut pushes off a space shuttle. If the astronaut has a mass of 75kg and the shuttle has a mass of 2000kg, what can be said about the forces acting on both during this action?
Show hintHide hint
Consider Newton's Third Law and how mass affects acceleration.
