Friction
An object in motion will stay in motion. The term to describe this
What is Inertia
True or False: An unbalanced force doesn't affect motion.
What is False

What is B.Oil on a squeaky door hinge?
What is the measurement of the force of gravity on an object?
What is weight
True or False: An object decreases speed over time on a tile surface. This is an example of the object losing force.
What is False.
In a warehouse, the workers sometimes slide boxes along the floor to move them. Two boxes were sliding toward each other and crashed. The crash caused both boxes to change speed. Based on the information in the diagram, which statement is correct? In your answer, explain what the forces were like and why the boxes changed speed.
What is Box 1 has more mass than Box 2
Three objects of the same mass experience different changes in velocity? Which object experienced a great force?
What is the object with the greatest change in velocity?
What is the force that acts between any two masses and pulls them together?
What is Gravitational force
Which of Newton's laws states: That an object at rest will stay at rest and an object in motion will stay in motion at a constant velocity, unless acted upon by an unbalanced force.
What is 1st?
What happens to objects of different masses when they collide?
What is the object with the greatest mass will have the smallest change in velocity and the object with the smallest mass will have a greater change in velocity.
True or False. Using snow tires on an icy road is an example of an object moving across a frictionless road?
What is False?
True or False: A corn dog will fall faster than a peanut?
What is False
A great change in speed of objects with any mass is associated with this
What is a strong force?
Newton's 3rd Laws states: That for every action there is an equal and opposite reaction. What is an example of an equal and opposite reaction we learned?
What is a collision?
______is a force that does not cancel one another out.
What is unbalanced force?
True or False: Friction can create heat and cause objects to speed up or stop completely.
What is False.
A ball thrown horizontally without the presence of gravity and air resistance will...
What is continue moving horizontally?
Speed is directly associated with the amount of force exerted on an object. It is also associated with this
What is kinetic energy?
What is a rule I can use to determine which object of the same mass experienced a strong force?
What is if the objects have the same mass and same change in velocity they all experienced the same strength force?
