Question

1. when you push against a wall, the wall pushes back with a) less force than you apply b) the same force you apply c) no force at all d) double the force you apply answer the following questions in complete sentences. 11. explain in your own words how gravity affects the orbits of planets around the sun. 12. describe a real - life example of newtons first law of motion. 13. why is it important to wear a seat belt in a moving car, according to newtons laws? show your work for each question using the equation force = mass * acceleration. 14. a soccer ball has a mass of 0.45 kg. if a player kicks it and the ball accelerates at 18 m/s², what is the force applied to the ball? 15. a train car has a mass of 2,500 kg and accelerates at 0.8 m/s² as it leaves the station. as it does this, it is pushing with a force against the rails. how much force is it pushing with? 16. a student pushes a box with a force of 30 n, causing it to accelerate at 2 m/s². what is the mass of the box?

Step1: Recall Newton's third - law

Newton's third law states that for every action, there is an equal and opposite reaction. When you push against a wall, the wall pushes back with the same force you apply.

Gravity is a force of attraction between two masses. The Sun's gravity pulls on the planets, causing them to follow curved paths (orbits) instead of moving in straight - lines. The strength of the gravitational pull depends on the mass of the Sun and the distance of the planet from it.

Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. A book on a table remains at rest until a force (like someone picking it up) acts on it.

Answer:

b) The same force you apply
