Newtons Third Law (GCSE Physics)

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

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

A swimmer accelerates forward by pushing water backwards. If the swimmer exerts 60 N on the water for 0.5 s and the swimmer’s mass is 75 kg, what is the change in the swimmer’s momentum?

A person standing on ice skates gently pushes a stationary friend. The pusher feels a force backward and moves backward. Which law explains why both move apart even though only one pushed?

A person pushes a heavy crate across the floor with a 150 N horizontal push; the crate pushes back with 150 N. If the person’s feet push the ground, what is the role of that ground force in causing motion?

A 5 N force from object A acts on object B to the right. What force does object B exert on object A?

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

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