Newtons Third Law (GCSE Physics)

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 car of mass 1200 kg collides with a barrier and experiences an average force of 6000 N backwards for 0.2 s. According to Newton’s Third Law, what force does the car exert on the barrier during the collision?

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 soccer player kicks a ball; the player’s foot exerts a force on the ball for a short time. Which statement follows Newton’s Third Law?

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 boy pushes a stationary shopping trolley; he exerts 40 N on the trolley. According to Newton’s Third Law, what force acts on the boy?

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?

When a tennis player serves, racquet exerts a large force on ball. Which statement about energy and Newton’s Third Law is correct?

Two ice blocks collide; the force between them is internal to the two-block system. What does Newton’s Third Law say about these forces?

A truck of mass 4000 kg collides with a car of mass 1000 kg. During the brief interaction, the force on the truck is –8000 N (backwards). What is the force on the car during that interaction?
