Newton's First Law
Newton's First Law is also known as the Law of ______________.
What is inertia?
The rate at which velocity changes.
What is acceleration?
Newton's Third Law states...
What is for every action there is an equal and opposite reaction?
A soccer ball travels at a constant speed in the same direction.
What is Newton's First Law?
Inertia is...
What is the tendency of an object to resist a change in motion?
What is the difference between mass and weight?
What is weight is (usually) the force upon an object due to gravity and mass is the quantity of matter in an object?
How many forces are involved in an interaction?
What is at least two forces?
A rocket launches.
What is Newton's Third Law?
An object is in equilibrium when...
What is the net force on that object equals zero?
Newton's Second Law relates which three variables?
What is force, mass, and acceleration?
How can the acceleration of an object with a large mass equal the acceleration of an object with a small mass? (think of equivalent fractions)
What is the forces are proportional to the mass?
A heavy weight and a bouncy ball drop at the same acceleration.
What is Newton's Second Law?
What is the net force is zero? Gravitational force and support force cancel out.
How are acceleration and mass related?
What is an inverse relationship? (acceleration ~ 1/mass)
You hit a baseball with a baseball bat. Which is the action and which is the reaction?
What is bat hitting ball as action and ball hitting bat as reaction?
A table cloth pulled quickly from underneath dishes.
What is Newton's First Law?
Explain the forces acting on an object in dynamic equilibrium.
What is the net force on the object equals zero? Gravitational force and support force cancel out; applied force and friction cancel out.
How are acceleration and force related?
What is a directly proportional relationship? (a ~ F)
A soccer ball is kicked with a force of 5 N on one side and is kicked simultaneously with a force of 5 N on the opposite side. What is the acceleration of the soccer ball?
Pedaling a bicycle.
