7 Science Forces & Motion

What is the formula to calculate force?

• F = m - a

• F = m x a

• F = m / a

• F = m + a

What is the SI unit of force?

• Meters

• Pounds

• Newtons

• Kilograms

If an object has a mass of 3 pounds, what is its mass in kilograms?

• 3.00 kg

• 2.54 kg

• 4.00 kg

• 1.36 kg

How do you convert weight in Newtons to mass in kilograms?

• Subtract 9.8

• Add 9.8

• Divide by 9.8

• Multiply by 9.8

What is the acceleration of a 130 kg object pushed by a man with 650 Newtons of force?

• 2.5 m/s²

• 3.5 m/s²

• 4.5 m/s²

What is the mass of an object if its weight is 10 N?

• 3.00 kg

• 2.00 kg

• 0.98 kg

• 1.02 kg

What is the acceleration of a 1,000 kg car if it requires a force of 5,000 N?
