Newton’s 2nd Law of motion states – Complete the sentence: The greater the force that is applied to an object, the the acceleration. However, if that same force was applied to an object with a larger mass, it will have a accerleration.

Using the formula for the 2nd Law, force = mass x acceleration, calculate the three problems below:

An object with a mass of 5.0 kg accelerates 8.0 m/s2 when an unknown fore is applied to it. What is the amount of the force?

An object with a mass of 3.2 kg has a force of 7.3 newtons applied to it. What is the resulting acceleration of the object?

An object accelerates 16.3 m/s2 when a force of 4.6 newtons is applied to it. What is the mass of the object?

Newton’s 3rd Law of motion states –

Based on Newton’s 3rd Law of motion, if an archer shoots an arrow at the target, the action force is the bowstring against the arrow. Explain where the reaction force can be found.

Based on Newton’s 3rd Law of motion, if a baseball player hits a ball with the bat, the action force is the impact of the bat against the ball. Explain where the reaction force can be found.

If a bowler rolls the bowling ball down the alleyway with a force of 1,000N. The ball exerts a reaction force again the alleyway with approximately how much force? Explain your thinking behind this.

The gravity of Earth is attracting a person towards the center with 500N of gravitational force. The person is exerting a reactionary force on the Earth with how much force? Explain your thinking behind this.
