According to this law, the acceleration of an object depends on the mass of the object and the amount of force applied.
What is Newton's Second Law of Motion (F=ma)?
This is a force between two surfaces rubbing against each other. It works against the motion of an object.
What is friction?
This force opposes the motion of an object sliding on a surface.
What is friction?
This law states that an object will remain at rest or in uniform motion unless acted upon by an external force.
What is Newton's First Law of Motion?
Sandley started pushing a bookcase across the room.Then, he removed the books and continued pushing with the same force and direction. How does removing the books affect the motion of the bookcase?
What is the mass is decreased, making the bookcase move faster?
This law states that an object at rest will stay at rest unless acted upon by an external force.
What is Newton's First Law of Motion?
This term refers to the tendency of an object to resist changes in its state of motion.
What is inertia?
The type of force which results in movement?
What is an unbalanced force?
If you push a stationary box and it starts moving, this is an example of overcoming ____.
What is inertia?
The term used to describe how far an object has moved is ____.
What is distance?
Some students apply force to a toy car on a ramp to push it down. The students measure how fast the car rolls down the ramp. If students want to increase the speed of the car down the ramp, what should they do?
What is increase the force applied to the car.
This is a measure of how much matter is in an object.
What is mass?

The speed and direction of an object is known as its ____.
What is velocity?
What two forces are acting together to keep a cup balanced on a table?
What is gravity pulling the cup down toward the table and the force of the table holding the cup up?

What is the truck has more mass?
Which type of force moves an object toward the source of the force?
What is pull?
