Describe what the forces must be like if two teams are playing tug-of-war and the rope is not moving. LT 2: I can explain real world examples of balanced and unbalanced forces and their effect on the motion of objects. During a game of tug-of-war the team on the right is beating the team on the left. Describe the forces on the rope. LT 3: I can demonstrate and calculate how unbalanced forces change the speed or direction of an object’s motion. If this object started at rest – which direction would it move according to this diagram? LT 4: I can label and diagram the forces acting on an object and calculate the net force and direction of the object. One student pushes a box with 10 N to the right. Another student on the other side pulls in the same direction with 5 N. Finish the force diagram and calculate the Net Force. 100 N 5N 5N FNET=_______ How does a balanced or unbalanced force affect the motion of an object? How can net force be calculated? 4 3 2 1 8.6B I can explain the differences between speed, velocity, and acceleration and give examples of each. 4 3 2 1 8.6B I can recognize real-world examples of speed, velocity, and acceleration. 4 3 2 1 4 3 2 1 Speed: Example: Velocity: Example: Acceleration: Example: Name ___________________________________ Date _____________________ Period ________ Position: Example: Motion: Example: LT 5: I can explain the differences between speed, velocity, and acceleration and give examples of each. 1. What does velocity have that speed does not have? 2. Changing speed is one example of acceleration. What else could change for an example of acceleration? LT 6: I can recognize real-world examples of speed, velocity, and acceleration. Next to each example write if it’s for Speed, Velocity, or Acceleration. A plane flies to the north at 250 miles per hour _______________ A jogger starts to get tired and slows down ______________ Mike can walk two blocks in 5 minutes____________ What are the differences between speed, velocity and acceleration? 4 3 2 1 8.6C I can categorize real life examples by the Laws of Motion which they exhibit. 4 3 2 1 4 3 2 1 4 3 2 1 4 3 2 1 8.6C I can investigate and describe applications of Newton’s law of inertia, law of force and acceleration (F=MA), and law of action/reaction 4 3 2 1 8.6C I can compute speed and acceleration of moving objects using the equation from Newton’s 2nd law. Inertia: Example: Friction: Example: Newtons: Example: Spring Scale: Example: LT 7&8: I can investigate and describe applications of Newton’s law of inertia, law of force and acceleration (F=ma), and law of action/ reaction. Next to each example write which law applies: A small car takes a short time to stop but a large train takes miles to stop. ____________ A rocket fires down but the rocket goes up. ___________ A car crashes and stops but the driver continues to move forward through the windshield ___________ LT9: I can compute speed and acceleration of moving objects using the equation from Newton’s 2nd law. A toy car has a mass of 50 kg. A child pushes on the car with a force of 100 N. At what rate will the car accelerate? (Please be sure your answer has a unit of measurement with it) How does the mass of a body at rest affect its tendency to remain at rest? How does the force required to move an object change with mass? How does the force acting on an object affect its tendency to remain at rest? How do Newton’s Laws of Motion affect everyday situations?
