Sort each of the following examples into the correct Law of Motion column. Remember:Newton's 1st Law states: An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force.Newton's 2nd Law states: Force is equal to the mass of an object times the acceleration of the object.Newton's 3rd Law states: For every action, there is an equal but opposite reaction. 1st Law of Motion An object at rest stays at rest unless acted on by an outside force Someone crashes their bike and is thrown over it on to the ground The law also known as the law of inertia An object in motion stays in motion unless acted on by an outside force A soccer ball will not move until a player kicks it In a plane taking off, you feel pushed back into your seat 2nd Law of Motion You have to push a heavy ball harder to get it to move as fast as a small one More force = More acceleration Force = mass * acceleration It takes less force to push a bike than a motorcycle 12 lb bowling ball goes faster down the lane than a 15 lb bowling ball A boy can throw a football farther than his friend because he uses more force Push a large box and a small box with the same force; the small box will go faster 3rd Law of Motion If air is let out of a balloon quickly, air pushes down and balloon goes up Feet push down on the floor and the floor pushes up on the feet as you walk When you paddle a canoe, the canoe goes forward A fireman turns on hose and is knocked backwards For every action there is an equal and opposite reaction When you push on a door, it pushes back with equal and opposite force You push against the wall in the pool and you move forward. As the mass on the wagon increases, the wagon accelerates less. As the mass on the wagon decreases, the wagon accelerates less. As the force of the push on the wagon decreases, the wagon accelerates more. As the force of the push on the wagon increases, the wagon accelerates more. Block 2 will have a greater acceleration than Block 3. Block 1 will have a smaller acceleration than Block 3. Block 2 will have a smaller acceleration than Block 4. Block 1 will have a greater acceleration than Block 2. Intertia Matching Rank the following masses from most inertia (1) to least inertia (4):145 gram baseball, 8200 gram bowling ball, 50 gramgolf ball, 540 gram croquet ball 1-most inertia bowling ball 2-second most inertia croquet ball 3-third most inertia baseball 4-least inertia golf ball Acceleration Matching Rank the following masses from least acceleration (1) to most acceleration (4) when a force is applied:145 gram baseball, 8200 gram bowling ball, 50 gram golf ball, 540 gram croquet ball 1-least acceleration bowling ball 2-second least acceleration croquet ball 3-third least acceleration baseball 4-most acceleration golf ball Cart 2 will be slower than cart 1. Cart 2 will move faster than cart 1. Cart 1 and 2 will move at the same speed. Cart 1 and 2 will remain at rest.
