Why will it take more force to accelerate a box with the mass of 1000 grams than a box with the mass of 100 grams.

• Because it has less mass

• Because it has more newton's

• Because it has more mass

Would it be harder to stop a car with a mass of 800 kg car moving with a deceleration of 8 m/s² or a truck with a mass of 5,000 kg is moving with a deceleration of 3 m/s² ?

• The truck is much harder to stop

• The car is much harder to stop

• It takes the same amount of force to stop both
