• up with 10N of force

• down with 5N of force

• left with 10N of force

• right with 10N of force

Inertia depends on __________.

• Weight

• Velocity

• Mass

• Acceleration

Newton's second law states.....

• If there is more mass then there is more acceleration

• An object at rest wants to be in motion

• Force = Mass x Acceleration

• The force exerted on an object is not related to mass or acceleration

An object with a mass of 100 kg is observed to accelerate at the rate of 5 m/s2. Calculate the force required to produce this acceleration.

• 20N

• 500 M/S

• 500 Kg

• 500N
