If a 10 kilogram object accelerates suddenly at 15 m/s². How much FORCE was applied to the object?

• 10 × 15 = 150 Newtons

• 10 ÷ 15 = 0.67 Newtons

• 15 ÷ 10 = 1.5 Newtons

A 20 kg bike accelerates at 10 m/s². What is the FORCE?

• 20 × 10 = 25 Newtons

• 20 ÷ 10 = 2 Newtons

• 20 × 10 = 200 Newtons

• 10 ÷ 20 = 0.50 Newtons

The MASS of a car is 1000 kg. HOW MUCH FORCE would be required to ACCELERATE the car at a rate of 3 m/s²?

• 1000 ÷ 3 = 333 N

• 3 ÷ 1000 = 0.003 N

• 1000 x 3 = 3000 N

A FORCE of 20 N was applied to an object, which caused it to accelerate at 5 m/s² . What was the MASS of the object?

• 20 x 5 = 100 kg

• 20 ÷ 5 = 4 kg

• 5 ÷ 20 = 0.25 kg
