What is a force?, a push or pull that can change the shape of an object, something that pulls you down to earth, friction, what is force measured in ?, Pascals (Pa), grams (g), joules/kilojoules (J/kj), Newtons (N), what does balanced mean ?, no change in motion, change in motion, both sides are equal, unbalanced acceleration (speeding up, slowing down or changing direction), Types of forces : CONTACT , thermal, electricity , friction, tension, gravity, magnetism, types of forces : NON CONTACT, friction, tension, gravity, magnetism, thermal, electricity, series circuit (choose 2), one path, multiple paths, if one bulb breaks, they all go off, if one bulb breaks, the others stay on, parallel circuit (choose 2), multiple paths , if one bulb breaks, they all go off, one path, if one bulb breaks, the others stay on, voltage (v), F = m x a, electric potential difference , V = I x R, flow of charge, what is this ?, light switch, bulb, cell, switch, what is this ?, buzzer, battery, swtich, wire, what is this ?, lightswitch, bulb, voltmeter, ammeter , if the area is small (like a sharp knife) the pressure is ..., small, the same, spread , high, if the area is wide (snowshoes) the pressure is ..., spread, low, high, the same, increase force , decreases pressure, increases pressure, decrease area, decreases pressure, increases pressure, wider area , decreases pressure, increases pressure, what is the unit for pressure , Newtons (N), grams (g), joules/kilojoules (J/Kj), Pascals (P), How do you calculate pressure?, P = F/A, P = F*A, F-A = P, P = A+F, action reaction, objects resist change , every force has an equal opposite, f = m x a , change direction.
