Force and motion review

  1. 1. Force and Motion Test Review
  2. 2. Distance a Bus Travels Determine the acceleration of the bus. There is no acceleration because the bus moves at a constant speed and the direction cannot be determined.
  3. 3. What is the acceleration of a 4000kg plane that has a force on it of 24,000N? A=F/m A = 24,000N / 4000kg A = 6 m/s2
  4. 4. Speed (km/h) Interpret the data on the graph at each point. 1 2 3 Distance (km) 1. The object is decelerating slowly as the distance increases. 2. The object decelerates more quickly. 3. The object decelerates more slowly as moves farther away from its starting point.
  5. 5. If a force of 20N causes a ball to accelerate at a rate of 1.5 m/s2, what is the mass of the ball? Round to the nearest hundredth. M=F/a M = 20N / 1.5m/s2 M = 13.33 kg
  6. 6. A motorcycle is moving west on a road at 80km/hr. The driver notices a police officer and lets off of the throttle. Describe what happens to its speed and velocity. The speed of the motorcycle decreases. Therefore the velocity of the motorcycle changes even though the direction remains constant.
  7. 7. Describe the motion of the train. The train is moving left with a net force of 3N.
  8. 8. Objects are affected by friction when they move across other surfaces. Describe what friction is and what this causes. Friction is the force between surfaces that resists the movement of one surface past another surface. It will cause an object to slow down or stop moving.
  9. 9. What is the speed of a sailboat that is traveling 100 meters in 120 seconds? Round to the nearest hundredth. S=D/t S = 100m / 120s S = .83 m/s
  10. 10. Describe the difference between acceleration and velocity. Velocity is a speed and direction at any given time. Acceleration is a change in velocity; basically, acceleration describes if an object has sped up, slowed down, stopped moving, or changed direction.
  11. 11. Find the car’s average speed at 10 seconds. 2 4 6 Time (s) 8 S = D/t S = 25m / 10s S = 2.5m/s 10
  12. 12. How much force must be applied to a toy car that has a mass of 2.5kg to achieve an acceleration of 2.4m/s2? F=mxa F = 2.5kg x 2.4m/s2 F = 6N
  13. 13. Name at least one force the causes a bicycle to stop moving. The tires of the bicycle rolling across the ground experience friction, a force that resists this movement. It causes the bicycle to slow down. The bicycle and rider may encounter air resistance, a fluid friction force that resists movement by pushing against an object. It causes the bicycle to slow down.
  14. 14. At a speed of 7.5 m/s, how far can you run in 40 seconds? D=sxt D = 7.5m/s x 40s D = 300m
