Momentum

(Four assignments listed below) Momentum BW1: 1 Momentum is the amount of motion of an object. 2 Momentum depends on both mass and velocity. 3 Momentum is measured in kilogram-meters per second. 4 The momentum of an object is in the same direction as its velocity. 5 The total momentum of any group of objects remains the same without an outside force. End ............................................ Momentum BW2: 1 Momentum is mass in motion 2 (kg-m/s) = (kg) x (m/s) (Put units below the correct terms) (Example of reasoning) 3 Shared motion may not be noticed. (1 Idea) 4 A cannonball drops beside a horse both when it is stationary and when it is moving. (2 Evidence) 5 Relative to the motion of the horse, the cannon ball drops the same whether the horse is moving or not, so the horse’s motion is not noticed. 6. Likewise, Everything on Earth shares the motion of the Earth, so the motion of the Earth is not noticed. (3 Links the idea & evidence to the claim) end ........................................... Calculate Momentum1: 1 Momentum = Mass x Velocity 2 Which has more momentum: a 3.0-kg hammer swung at 1.5-m/s, or a 4.0-kg hammer swung at 0.9-m/s? 3. Hammer 1: Mass = 3.0-kg Velocity = 1.5-m/s Momentum = 3.0-kg x 1.5-m/s = 4. Hammer 2: Mass = 4.0-kg Velocity = 0.9-m/s Momentum = 4.0-kg x 0.9-m/s = 5. Does this make sense? Is it possible for the smaller hammer to have more momentum because... End .......................................... Calculate Momentum 2: (Fill in the blanks) Speed X Mass = Momentum 1. Does the golf ball or base ball have more momentum? A) Speed and mass of the golf ball are... b) .....m/s x ..... kg = ......kg-m/s for the golf ball C) Momentum = ...... for the golf ball A) Speed and mass of the baseball are... b) .....m/s x ..... kg = ......kg-m/s for the Baseball C) Momentum = ...... for the Baseball 2. What is the momentum of the bird? A) Mass and speed of the bird are... B) .....m/s x ..... kg = ......kg-m/s for the bird c) Momentum = ..... kg-m/s for the bird end...........................................................................................

Why can't we feel the spin of the Earth or it's effects. []
