Force Calculation 1Force Calculation 1

• An object has a mass of 50 kg and moves with an acceleration of 5 m/s2. What is the amount of force the object has?

• An object has a mass of 50 kg and moves with an acceleration of 5 m/s2. What is the amount of force the object has?

Force Calculation 2Force Calculation 2

• If an object accelerates at a rate of 7 m/s2 and has a mass of 75 kg, what is the amount of force the object has?

• If an object accelerates at a rate of 7 m/s2 and has a mass of 75 kg, what is the amount of force the object has?

Force Calculation 3Force Calculation 3

• A car is waiting at the starting line with a mass of 400 kg. How much force does the car have?

• A car is waiting at the starting line with a mass of 400 kg. How much force does the car have?

Force Diagram 1 AnswerForce Diagram 1 Answer

• Net Force = Force 1 – Force 2 • Net Force = Force 1 – Force 2 Net Force = 65 N Left – 15 N Right

Net Force = 50 N Left

Force Diagram 2 AnswerForce Diagram 2 Answer

• Net Force = Force 1 – Force 2 • Net Force = Force 1 – Force 2 Net Force = 30 N Down – 40 N Up

Net Force = 10 N Up

Force Diagram 3 AnswerForce Diagram 3 Answer

• Net Force = Force 1 + Force 2 • Net Force = Force 1 + Force 2 Net Force = 2 N Right + 76 N Right

Net Force = 78 N Right

Force Diagram 4 AnswerForce Diagram 4 Answer• Net Force 1 = Force 1 – Force 2 • Net Force 1 = Force 1 – Force 2

Net Force 1 = 10 N Left – 10 N Right

Net Force = No Motion

Net Force 2 = Force 3 – Force 4

Net Force 2 = 10 N Up – 10 N Down

Force Diagram 5 AnswerForce Diagram 5 Answer• Net Force 1 = Force 1 + Force 2 • Net Force 1 = Force 1 + Force 2

Net Force 1 = 90 N Right + 15 N Right

Net Force = 105 N Right

Net Force 2 = Force 3 – Force 4

Net Force 2 = 25 N Up – 25 N Down

Force Calculation 1Force Calculation 1

• Force = mass x acceleration• Force = mass x accelerationForce = 50 kg x 5 m/s2

Force = 250 Newtons

Force Calculation 2Force Calculation 2

• Force = mass x acceleration• Force = mass x accelerationForce = 75 kg x 7 m/s2

Force = 525 Newtons

Force Calculation 3Force Calculation 3

• Force = mass x acceleration• Force = mass x accelerationForce = 400 kg x 0 m/s2

Force = 0 Newtons
