Can you imagine how much force it would take to move this truck? How fast do you think you could accelerate it?

Newton’s Second Law of Motion How fast does it go?

Newton’s 2nd Law of Motion: The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma)

Acceleration depends on Force an objects acceleration increases (or decreases) as the force applied to the object increases (or decreases) Acceleration is DIRECTLY related to the force on the object. Large Force = Large Acceleration F a Small Force = Small Acceleration F a

a F F Acceleration depends on Mass an objects acceleration decreases (or increases) as its mass increases (decreases) Acceleration is INVERSELY related to the mass of the object. Example: When a shopping cart is empty (less mass), it is easy to push (accelerate) As you add objects to the cart (increase the mass), it becomes more difficult to push (accelerate) F Large Mass a Small acceleration F Small Mass Large acceleration a

Calculating Force, Mass, & Acceleration

Mike's car, which weighs 1,000 kg, is out of gas Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Using Newton's Second Law, can you compute how much force Mike is applying to the car. FORCE = MASS times ACCELERATION Remember that: Mass is measured in (g) or (kg) Acceleration is measured in (m/sec2) Force is measured in Newtons (N) Answer = 50 N
