Newton's Laws of Motion Practice

Identify Newton's Laws of MotionFirst Law: An object at rest will remain at rest and an object in motion will remain in motion at the same speed and in the same direction unless acted upon by an unbalanced force.Second Law: Acceleration of an object depends on the force acting on it and its mass. Force = mass x accelerationThird Law: For every action force there is an equal and opposite reaction force. 1. A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them. This is an example of Newton's _ law. first second third 2. Pushing a child on a swing is easier than pushing an adult on the same swing because the adult has more mass. This is an example of Newton's _ law. first second third 3. A student leaves a pencil on a desk and the pencil stays in the same spot until another student picks it up. This is an example of Newton's _ law. first second third 4. A soccer player kicks a ball with her foot and her toes are left stinging after the kick. This is an example of Newton's _ law. first second third 6. Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction. This is an example of Newton's _ law. first second third 7. A picture is hanging on a wall and does not move. This is an example of Newton's _ law. first second third 8. A volleyball accelerates more than a bowling ball when thrown with the same force. This is an example of Newton's _ law. first second third 9. A passenger in a car not wearing a seatbelt will fly forward when the driver slams on the brakes. This is an example of Newton's _ law. first second third 10. A swimmer uses his arms to push the water backward which propels him to move forward. This is an example of Newton's _ law. first second third A bowling ball has a mass of 5 kg and is accelerating at a rate of 4 m .The force applied to the bowling ball is . . . 12 N 9 N 20 N 1.25 N These two pictures are an example of which of Newton's Laws? 1st Law 2nd Law 3rd Law 4th Law When forces are balanced they are . . . equal but opposite equal and in the same direction unequal and opposite unequal and in the same direction Ms. Hendrickse pushes a student across the classroom in the rolling chair. The chair comes to a complete stop but the student continues to move forward because of acceleration velocity inertia An object accelerates at 3 m when a force of 6 newtons is applied to it. What is the object's mass? 2 N 2 kg 0.5 kg 18 N A force of 20 N acts on a 5 kg block. Calculate the acceleration of the object. m 100 m 4 m 4 kg 25 kg
