  1. What net force is required to accelerate a car at a rate of 2 m/s2 if the car has a mass of 3,000 kg? What do we know??? F= M= 3000kg A= 2m/s2 F= 3000 X 2= 6000N ❓ Net Force is measured in Newtons (N). Mass is measured in Kilograms (kg). Acceleration is measured in meters per second squared (m/s2)

  2. What force does Mr. Billmyer need to produce in order to throw his 10 kg bowling ball down an alleyway with an acceleration rate of 3 m/s2? What do we know??? F= M= A= ❓ Net Force is measured in Newtons (N). Mass is measured in Kilograms (kg). Acceleration is measured in meters per second squared (m/s2)

  3. Ms. Lay has a car that accelerates at 5 m/s2. If the car has a mass of 2000 kg, how much force does the car produce? What do we know??? F= M= A= ❓ Net Force is measured in Newtons (N). Mass is measured in Kilograms (kg). Acceleration is measured in meters per second squared (m/s2)

  4. What is the mass of a falling rock if it produces a force of 147 N (acceleration of gravity is 9.8 m/s2)? What do we know??? F= M= A= ❓ Net Force is measured in Newtons (N). Mass is measured in Kilograms (kg). Acceleration is measured in meters per second squared (m/s2)

  5. What is the mass of Mr. Kelly’s truck if it produces a force of 14,000 N while accelerating at a rate of 5 m/s2 ? What do we know??? F= 14,000N M= A= 5 M/S2 14O00/5= 2800KG ❓ Net Force is measured in Newtons (N). Mass is measured in Kilograms (kg). Acceleration is measured in meters per second squared (m/s2)

  6. What is the acceleration of a softball if it has a mass of 0.5 kg and hits Mrs. Rott’s catcher's glove with a force of 25 N? What do we know??? F= 25N M= .5kg A= 25/.5=50M/S2 ❓ Net Force is measured in Newtons (N). Mass is measured in Kilograms (kg). Acceleration is measured in meters per second squared (m/s2)

  7. Mr. Lentz’s car has a mass of 2000 kg. If his car produces a force of 8500 N, how fast will it accelerate? What do we know??? F= M= A= ❓ Net Force is measured in Newtons (N). Mass is measured in Kilograms (kg). Acceleration is measured in meters per second squared (m/s2)
