What is a force according to Newton’s first law of motion?A push or pull that always changes an object’s speedSomething that keeps an object stationary foreverAn interaction that can change an object’s state of motionA property that only affects moving objectsQuestion 1 of 202. What happens to an object in motion when no force is acting on it?It slows down and stopsIt continues moving with the same speed and directionIt changes direction randomlyIt acceleratesQuestion 2 of 203. Which of the following is an example of a contact force?Magnetic forceGravitational forceMuscular forceElectrostatic forceQuestion 3 of 204. What type of force attracts iron nails to a magnet?Contact forceMuscular forceMagnetic forceFrictional forceQuestion 4 of 205. Why does a ball stop after being pushed on a table?Due to gravitational forceDue to frictional forceDue to magnetic forceDue to electrostatic forceQuestion 5 of 206. What happens if there is no friction while walking?We walk fasterWe slip and cannot walkWe float in the airWe move backwardQuestion 6 of 207. In the experiment with two floating bottles and magnets, what causes them to move toward each other?Contact forceGravitational forceMagnetic force between unlike polesFrictional forceQuestion 7 of 208. What is the result when equal masses are placed in pans tied to a cardboard box?The box moves to the heavier sideThe box does not moveThe box moves upwardThe box spinsQuestion 8 of 209. What happens when unequal forces are applied to a box on a table?The box remains stationaryThe box moves in the direction of the greater forceThe box moves upwardThe box moves in a circleQuestion 9 of 2010. Why does a rope in a tug of war not move if the pull is equal on both sides?The forces are unbalancedThe forces are balancedFriction is absentGravity pulls it downQuestion 10 of 2011. What is the tendency of an object to remain in its existing state called?PressureInertiaFrictionBuoyancyQuestion 11 of 2012. In the coin and postcard experiment, why does the coin fall into the glass?Due to magnetic forceDue to inertia of restDue to gravitational force aloneDue to frictional forceQuestion 12 of 2013. What type of inertia causes passengers to jerk forward when a bus stops suddenly?Inertia of restInertia of motionDirectional inertiaInertia of pressureQuestion 13 of 2014. Why do we use a sharp knife to cut vegetables easily?It increases the area of contactIt reduces the pressureIt increases the pressureIt reduces the forceQuestion 14 of 2015. What is the SI unit of pressure?NewtonPascalkg/m³N/m³Question 15 of 2016.
