State Newton's second law in terms of resultant force, mass, and acceleration, Resultant force equals mass times acceleration, A 2 kg trolley accelerates at 3 m/s². Find the resultant force, 6 N, A car of mass 1200 kg has a resultant force of 2400 N. Find its acceleration, 2 m/s², What is the resultant force on an object moving at constant velocity, Zero, A 5 kg box is pulled right by 20 N and friction is 8 N left. Find the acceleration, 2.4 m/s² right, Why does a passenger lurch forward when a bus stops suddenly, Inertia resists change of motion, What happens to acceleration if the same force acts on a larger mass, Acceleration decreases, A rocket expels gas backward. Which law explains its forward motion, Newton's third law, State Newton's first law of motion, Object remains at rest or moves with velocity if net force is zero, A 10 kg object has weight 100 N on Earth. Find gravitational field strength, 10 N/kg, A falling object has weight 50 N and air resistance 20 N upward. Find resultant force, 30 N downward, At terminal velocity, what is the relationship between weight and air resistance, They are equal, Why are seat belts important during sudden deceleration, They reduce effects of inertia, A 1500 kg car accelerates from rest to 20 m/s in 5 s. Find the resultant force, 6000 N, A boy pushes a wall but it does not move. What can be said about the forces, Forces are equal and opposite
