ByTwo long parallel wires 20 cm apart carry currents of 5A and 8A in the same direction. Is there any point between the two wires where the magnetic field is zero?. Yes, midway between the wires. Yes, 12 cm from the 5A wire. Yes, 7.7 cm from the 5A wire. No.

ByBalanced and Unbalanced Forces. When the forces acting on the car are balanced , the resultant force is zero. It stops accelerating and moves at a constant speed.

ByNewton’s First Law - Inertia. Chapter Four. Aristotle on Motion. Greek scientist – 400 BC Two types of Motion Natural – Straight-up motion (smoke) or straight-down motion (falling) or circular (planets) Objects would seek their “natural” resting places Not thought to be caused by forces.

ByBiomechanics 3. Composition of Forces. Daniel Jandačka , PhD. The net force is a vector produced when two or more forces act on a single object. It is calculated by vector addition of the force vectors acting on the object. Squat Jump of Shot P utter with barbell

ByForces on Submerged Surfaces in Static Fluids. We will use these to analyze and obtain expressions for the forces on submerged surfaces. In doing this it should also be clear the difference between: · Pressure which is a scalar quantity whose value is equal in all directions and,

ByNewton’s Laws of Motion. First Law. If there is no resultant force (overall force) on an object, it does not accelerate it continues to move with constant speed in one fixed direction The speed could be zero – i.e. it stays still . Second Law.
