Station 1 Calculation Station Formulas to be used: F = M×A A= M=F/A **Reminder: Acceleration due to gravity = 9.8m/s2** 1. 2. 3. Find the force acting on a 14 kg wagon that produces an acceleration of 1.5m/s2 A cat pushes a 0.25 kg toy with a net force of 8 N. According to Newton’s second law what is the acceleration of the ball? Kate applied a force of 10N on a tennis ball that was moving at a rate of 12m/s2. What is the mass of the tennis ball? Round to the nearest hundredth. Station 2 Friction and Net Force Calculate the net forces for the following examples and state whether they are balanced or unbalanced forces. Directions. For each picture, draw an arrow to show the direction of the frictional force. Then name the type of friction – static, sliding, or fluid – that is acting in each case. Arrow Direction – Type of Friction – Arrow Direction Type of Friction – Arrow Direction Type of Friction – Station 3: COLLISIONS 1. A collision occurs between two moving cars. What is the velocity of each car AFTER the collision? Before Collision 7 m/s 3 m/s On your paper determine the velocity of the vehicles after the collision. 2. A collision occurs between two cars that connect. What is the acceleration of each car AFTER the collision? Before Collision 12 m/s 0 m/s On your paper determine the velocity of the vehicles after the collision. 3. A collision occurs between one moving car. What is the acceleration of each car after the collision? Before Collision 16 m/s 0 m/s On your paper determine the velocity of the vehicles after the collision. 4. What is the momentum of a 12 kg bicycle moving at 5.5 m/s downhill? Show all work! Station 4: WHICH LAW Directions. Match each scenario with one of Newton’s Laws of Motion. Write the number 1 for Newton’s 1st Law Write the number 2 for Newton’s 2nd Law Write the number 3 for Newton’s 3rd Law 1.A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them. 2.A person’s body is thrown outward as a car rounds a curve on a highway. 3.Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction. 4.A person not wearing a seatbelt flies through a car window when someone slams on the breaks because the person’s body wants to remain in continuous motion even when the car stops. 5.Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia. 6.A soccer ball accelerates more than a bowling ball when thrown with the same force. 7. A soccer player kicks a ball with their foot and their toes are left stinging. 8. A student leaves a pencil on a desk and the pencil stays in the same spot until another student picks it up. Station 5 Chapter 2 Wrap Up 1. What force opposes motion? _____________________ 2. Unbalanced forces can cause an object to accelerate? What does it mean when an object accelerates? a. _______________ b. _________________ c. ________________ 3. In which of the pictures is the person applying more force? EXPLAIN! A B 4. Friction is an example of a contact force. What is an example of a noncontact force? _____________________________________________ 5. It would be harder to stop a basketball than a tennis ball. What is another way to say measure of how hard it is to stop a moving object? __________ 6. What is the force which allows the washing machine to spin clothes in a circle? _______________________________ Station 6 Newton’s 2nd Law Relationships 1. If Cathy had a mass of 72kg and traveled to the moon which has a gravitational acceleration of 1.6m/s2. Identify what her mass and weight would be on the moon. Show all work! 2. A teenager is buying their first car. They choose to purchase a car rather than an SUV because it gets more miles to the gallon when driving at the same acceleration. Force: ______________ Mass: _______________ Acceleration: _________________ What is the relationship between mass and force? ____________ 3. You have a friend who has a smaller mass than you, but they walk exerting the same amount of force as you. Why does your friend move faster than you? Force: _______________ Mass: _______________ Acceleration: _______________ What is the relationship between mass and acceleration? __________________ 4. You are playing ping pong with your friend. The mass of the ping pong ball is 5g. You notice an increase in acceleration of the ball when playing. What did you to your force? Force: ____________ Mass: _______________ Acceleration: _________________ What is the relationship between acceleration and force? ___________________
