Name the Law of Motion
What is the property of an object that resists change in its motion?
Inertia
What is a change in an object's position?
Motion
How do you know if an object has changed position?
Farther or closer from a reference point
Explain Newton's First Law of Motion.
An object in motion will stay in motion and an object at rest will stay at rest until an unbalanced force acts on it.
Explain Newton's Second Law of Motion.
The force of an object is equal to the mass times acceleration.
Which Newton's law of motion does the statement "forces occur in pairs" come from?
Newton's Third Law
Why are we able to walk on Earth?
Gravity
What is the distance traveled by an object per unit time called?
Speed
What are 3 ways in which the motion of an object might change as a result of an unbalanced force?
Speed up, slow down, or change direction
Why is friction considered a contact force?
Friction occurs when two objects are rubbing against each other.
Which Newton's Law of Motion has the formula F= mass times acceleration?
Newton's Second Law
What do forces both have?
Magnitude and direction
What is a force that resists motion created by objects rubbing together?
Friction
Explain the difference in balanced and unbalanced forces.
Balanced forces are equal and results in no change in motion. Unbalanced forces are not equal and result in change in motion.
What is the difference in potential and kinetic energy and how is this affected by balanced and unbalanced forces?
Potential energy is stored energy. There is no motion taking place. Since no motion is taking place the forces acting on it are balanced.
Kinetic energy is release energy. Energy in motion. You must have unbalanced forces.
Which Newton's law of motion describes action-reaction pairs?
Newton's Third Law of Motion
What is a force that pulls objects toward each other?
Gravity
True or False: Is a book resting on a desk an example of balanced force?
True
Newton's First Law is also known as the Law of ______.
Inertia
Two objects are being moved with the same applied force, but Object A has a mass of 10 grams and Object B has a mass of 15 grams. Based on Newton's Second Law, what can we conclude about the acceleration of these two objects.
Object B will require more force to accelerate because it has more mass. Object A will require less force.
For every action there is an equal and opposite reaction is which of Newton's Laws of Motion?
Newton's Third Law of Motion
What is a force that sets an object into motion?
Unbalanced force
Velocity is a measure of speed that takes into account the _________.
Direction of movement
What three things are the main focus of Newton's Second Law?
Force, Mass, and Acceleration
Explain the difference in balanced and unbalanced forces.
Balanced forces are equal and results in no change in motion.
Unbalanced forces are not equal and result in a change of motion.
