Newtons Third Law (GCSE Physics)

Two ice skaters push off each other; one skater has mass 50 kg and the other 75 kg. If they experience equal and opposite forces for the same short time, what can be said about their momenta after the push?

A swimmer pushes the pool wall with a force of 120 N to stop. The wall pushes the swimmer with 120 N. If the swimmer’s mass is 60 kg, what acceleration does the swimmer experience immediately after the push?

A swimmer pushes water backwards with a force to move forward. Which pair of forces illustrates Newton’s Third Law?

A person rests one hand on a wall and pushes with 20 N. According to Newton’s Third Law, what happens to the wall?

When a skateboarder pushes backward on the ground with a force of 120 N, which force acts on the skateboarder according to Newton’s Third Law?

A child on a swing pushes the air backwards with their hands while moving forward. Which best explains the forward motion using Newton’s Third Law?

A soccer ball hits the crossbar and rebounds with the same speed but opposite direction. Which is true about the forces during contact?

A rocket launcher fires a projectile. The launcher experiences recoil. Which describes the action–reaction pair during firing?

A rocket expels gas backwards. Which statement correctly applies Newton’s Third Law to the rocket and the expelled gas?

A hammer strikes a nail; the hammer feels a force on its head during impact. Why is this force equal to the force the hammer exerts on the nail?

A train engine pulls the wagons forward; each coupling exerts forces between engine and wagon. Which describes the forces at each coupling pair?
