Newton's Law of Motion Project
Newton's First Law
- An object at rest stays at rest and a object in motion stays in motion unless acted upon a unbalanced force.
Newton's First Law
A golf ball wont move off the tee unless the ball is struck by a golf club. The club is the unbalanced force and the golf ball is the object at rest. The picture with the coin and the glass shows that objects in motion stay in motion. The quarter is being pulled down by gravity. The quarter resists to move with the piece of cardboard and falls into the glass this is known as inertia. Inertia is the tendency of all objects to resist any change in motion.
Newton's Second Law
- The acceleration of an object depends on the mass of the object and the amount of force applied.
Newton's Second Law
Objects that have larger mass need a larger force to be pushed or pulled. This picture of the elephant shows us the first part of Newton's second law. The second picture shows that an object with a small mass and one with a large mass will accelerate differently if acted upon by equal forces. The acceleration of an object increases as its mass decreases. The acceleration of an object is always in the same direction as the net force applied.
Newton's Third Law
- Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force in the first.
Newton's Third Law
The space shuttle's thrusters push the exhaust gases downward. The gases push the shuttle upward with equal force. This shows the part of Newton's third law where there is every action there is an equal opposite reaction. Another example is the air in the balloon rushing out (action) and the balloon flying up (reaction). For every action there is an equal opposite reaction.
