This is the formula for average speed.
What is average speed=distance/time?
What is net force?
The change in position of an object over time.
What is motion?
This term describes the rate of change of velocity of an object.
What is acceleration?
This is the definition of force.
What is a push or a pull on an object?
This law states that an object at rest stays at rest unless acted upon by an unbalanced force.
What is Newton's First Law of Motion?
The force that pulls objects toward the center of the Earth.
What is gravity?
True or false: Balanced forces cause a change in motion.
What is false?
The difference between speed and velocity.
What is velocity includes the direction and a change in position over time, but speed is only a change in position over time.
This law states that for every action, there is an equal and opposite reaction.
What is Newton's Third Law of Motion?
If the amount of force applied increases, what happens to the acceleration?
What is increases?
Fill in the blanks: If both forces are going in the same direction, you ______ the forces. If both forces are going in opposite directions, you _______ the forces.
What is add, subtract?
This law states that 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?
What is friction?
This type of force acts at a distance without physical contact, such as magnetic or gravitational forces.
What is a non-contact force? (forces that act at a distance)

What is 3N to the left.
If an object has a mass of 10kg and is acted upon by a net force of 20N, what is its acceleration?
What is 2m/s2?
A car accelerates from 10 m/s to 37 m/s in 10 seconds. What is the acceleration in m/s2?
Please see slideshow for this question
What is 0N?
A car travels 150 kilometers in 2 hours. What is the average speed of the car during this trip?
What is 75km/h?
This is the equation associated with Newton's Second Law of Motion. Provide all three forms of the equation.
What is F=ma, m=F/a, a=F/m?
How can you determine if forces acting on an object are balanced or unbalanced?
Balanced = net force is zero
Unbalanced = net force is not zero
Jessica is comparing two balls. One ball has a mass of 1 kg, and the other has a mass of 2 kg. She pushes each with a force of 100 N. Which ball has the greater acceleration?
What is the 1kg ball?
If a soccer ball is at rest on the field, what must happen to it in order for it to start moving, and which of Newton's laws does this illustrate?
The soccer ball must be acted upon by an unbalanced force, such as a player kicking it. This illustrates Newton's First Law of Motion, which states that an object at rest will remain at rest unless acted upon by an unbalanced force.
Explain how Newton's Third Law of Motion is demonstrated when a swimmer pushes against the wall of a swimming pool.
When the swimmer pushes against the wall, they exert a force on the wall (action), and the wall exerts an equal and opposite force back on the swimmer (reaction), propelling them forward.
