What is the main difference between speed and velocity?, Speed included direction, while velocity does not., Velocity is measured in meters, while speed is measured in seconds., There is no difference, either one can be used in an experiment freely., Velocity includes speed and direction, whereas speed is just magnitude., An object accelerates uniformly from rest to a speed of 20 m/s in 4 seconds. What is the rate of acceleration?, 5m/s2, 80m/s2, 5m/s, 80m/s, Newton's First Law of Motion is also widely known as law of:, Universal Gravitation, Action and Reaction, Acceleration, Inertia, If a moving car suddenly stops and unbuckled passengers lurch forward, which physical principle explains this behavior?, Newton's Third Law, Newton's First Law, Newton's Second Law, Acceleration, A net force of 76 N is applied to a 4 kg box resting on a friction-less surface. What is the resulting acceleration of the box?, 304m/s2, 19m/s, 19m/s2, 304m/s, According to Newton's Second Law (\(F = ma\)), if you double the net force acting on an object while keeping its mass constant, what happens to its acceleration?, It doubles, It is cut in half, It quadruples, It remains unchanged, Which statement correctly summarizes Newton’s Third Law of Motion?, Action and Reaction forces always act on the same single object, resulting in zero net force., AN object in motion tends to stay in motion unless acted on by an outside force., The acceleration of an object is proportional to the net force and inversely proportional to its mass., For every action force, there is an equal and opposite reaction force acting on separate interacting objects., A hammer strikes a large iron nail with a force of 150 N. What is the magnitude of the force that the nail exerts on the hammer?, 0N, 150N, Less than 150N, Greater than 150 N,, What happens to an object's motion if it travels with a constant velocity?, It's acceleration is positive and increasing., Its net force is only pointing forward., It's acceleration is zero., Its speed is constantly increasing., Which of the following scenarios describes an object with a negative acceleration?, A car speeding up from 27 m/s to 33 m/s in 4 seconds., A car moving 35 m/s and applying breaks until it reaches 25 m/s., A car moving at a constant speed of 17 m/s in a straight line., A car reversing and increasing it's speed 12 m/s backwards.
