Level: Grade 7 science (Year 8 · Class 7) · Curriculum: MS-PS2-1, MS-PS2-2
What is the SI unit of force? Which of these is a non-contact force? A force of 25 N to the right and 25 N to the left act on a box. What is the net force? A box has 18 N to the right and 7 N to the left. What is the net force? A moving trolley has balanced forces on it. What does it do? You push a wall with 30 N. How hard does the wall push back? Which tool measures force? On a force diagram, what does the length of an arrow show? The same net force acts on a 1 kg trolley and a 4 kg trolley. Which changes its motion more? A spring stretches 2 cm with 4 N. How far does it stretch with 8 N, if the stretch is proportional to force? Define a force. — A push or a pull on an object. Unit of force? — The newton (N). Which instrument measures force? — A spring scale (newton meter). Give two contact forces. — Friction and tension, for example. Give two non-contact forces. — Gravity and magnetic force. How do you find net force on a line? — Add same direction, subtract opposite. What does zero net force mean for motion? — No change: at rest or steady speed. What does an unbalanced force do? — Changes speed or direction. Rule for interaction pairs? — Equal in size, opposite in direction, on different objects. Do you need a force to keep moving? — No, only to change the motion. Keep going with Lina
