What Do U Call It? Newton Says Newton’s Figs Name that Newton Be the Ball 100 pt 100 pt 100 pt 100 pt 100 pt 200 pt 200 pt 200 pt 200 pt 200 pt 300 pt 300 pt 300 pt 300 pt 300 pt 400 pt 400 pt 400 pt 400 pt 400 pt 500 pt 500 pt 500 pt 500 pt 5001 pt The force that opposes motion 2 What is friction? 3 A measure of inertia 4 What is mass? 5 Tendency to resist changes in motion 6 inertia 7 Measures changes in velocity 8 What is acceleration? 9 Property of moving objects that depends on mass and velocity 10 What is momentum? 11 What an object at rest will do 12 What is stay at rest (or not move) according to Newton’s First Law? 13 How to make an object accelerate twice as fast 14 What is apply twice as much force (or reduce the mass by half)? 15 How an object in motion will travel, according to Newton’s First Law 16 What is in a straight line and at a constant speed? 17 What has to be applied to an object to change its motion 18 What is a force? 19 When a soccer ball is kicked, the reason the action and reaction forces do not cancel each other out 20 What is they act on different objects? 21 Three properties involved in Newton’s Second Law 22 What are force, mass and acceleration? 23 To find the force, you would do this 24 What is multiply mass times acceleration? 25 The velocity of an object falling 1 second without any air resistance 26 What is 9.8 m/s? 27 What happens to acceleration when force increases and mass stays the same 28 What is it increases? 29 Why a rocket accelerates as it goes up – according to Newton’s second law 30 What is it loses mass (rocket fuel) so the same force makes it go faster? 31 The wall pushes back with an equal an opposite force when you push on it 32 What is Newton’s 3rd law? 33 An object NOT acted on by an unbalanced force will continue to move in a straight line at a constant velocity 34 What is Newton’s First Law 35 Two ways to describe the reaction force, according to Newton’s Third Law 36 What are equal in size and opposite in direction? 37 What happen when you toss a backpack while standing on a skateboard according to Newton’s Third Law 38 What is the force of the backpack pushes you in the opposite direction with equal force? 39 How the rocket is an example of Newton’s First Law 40 It won’t move without a force and only an unbalanced force will stop it from moving. 41 Why objects want to continue to travel in a straight line and at the same speed 42 What is they have inertia? 43 Mass times velocity is how to calculate this 44 What is momentum? 45 Two ways to increase momentum 46 What is increase mass or increase velocity? 47 When momentum is transferred between objects that collide but doesn’t change in amount 48 What is conservation of momentum? 49 Why you don’t want to play baseball with a bowling ball 50 What is it has more inertia so it is harder to catch and hit? 51
