Newton's laws practice

Master Newton's Laws! Practice force, mass, and acceleration calculations, plus vocabulary. Perfect for physics students.

For the following situations determine their force, mass or acceleration. Problem Unknown (force, mass, acceleration) lowercase answers Solution for unknown (just the number) An object with a mass of 7.0 kg accelerates 2.0 m when an unknown force is applied to it. force 14 An object accelerates 5.0 m when a force of 20.0 newtons is applied to it. mass 4 An object with a mass of 20.0 kg has a force of 5.0 newtons applied to it. acceleration .25 An object with a mass of 1500 g (grams) accelerates 10.0 m when an unknown force is applied to it. force 15,000 An object accelerates 16 m when a force of 4 newtons is applied to it. mass .25 Match the vocabulary word to it's definition inertia Tendency of a body to maintain is state of rest or uniform motion unless acted upon by an external force balanced forces Equal forces acting on an object in opposite directions unbalanced forces When the net forces on an object are greater than zero in one direction than in another, causing movement. velocity Speed of something in a given direction net force The sum of all forces acting on an object Match the definitions and examples with the newton's laws 1st law An object at rest will stay at rest, an object that is moving will stay moving unless disturbed by an unbalanced force A golfball sitting on top of a golf tee Bowling pins being hit by an unbalanced force of a bowling ball 2nd law Force is mass times acceleration An object with a mass of 5.0 kg accelerates 8.0 m when a force of 40N is applied to it. An object with a mass of 7.5 kg accelerates 8.3 m when a force of 63N is applied to it. 3rd law For every action there is an equal and opposite reaction A rocket taking off. Bouncing a basketball.
