Newton's Laws
In this law, an object only experiences a change in motion if another force acts upon it.
What is Newton's First Law?
This is the combination of all the forces acting on an object. It is usually indicated by a number and a direction.
What is the Net Force?
On a position-time graph, you see a diagonal line from 0s,0m going up to 3s, 60m. Calculate the average speed (no question needed).
20m/s
This type of force will cause an object moving along the ground on Earth to eventually come to a stop.
What is friction?
This type of energy is the stored energy that comes from an object being at a height with the possibility of dropping to Earth's surface. (Be specific. 3 words)
What is Gravitational Potential Energy?
In this law, an object's acceleration depends on the force of the push and the mass of the object being moved.
What is Newton's 2nd Law of Motion?
This is the International Standard (SI) unit to measure the strength of a force.
What is a Newton? (or N)
On a speed-time graph, what does an upward diagonal line from 0mph, 0s to 30mph, 6s represent?
Answer options: Speed up, Slow down, constant speed, object stopped
These two factors impact how strong the force of gravity is on an object suspended above Earth's Surface.
What is the distance (height) and mass of the object?
This is the type of energy that is stored when a spring is compressed.
What is Elastic Potential Energy?
In this law, every action has an equal and opposite reaction. It requires two objects pushing against each other to occur.
What is Newton's 3rd Law?
S = D / T is the formula for this.
What is speed? (average speed also accepted)
Which of the following would you see on the x-axis and y-axis of a speed-time graph?
x-axis: time, speed, or position
y-axis: time, speed, or position
x-axis: time
y-axis: speed
Examples of this type of force are magnetic, gravitational, and electrical.
What are some non-contact forces?
This law states that energy can neither be created nor destroyed, just transformed.
What is the Law of the Conservation of Energy?
The definition of this vocabulary word is the rate at which an object's velocity changes.
What is acceleration?
In tug of war, the forces towards the left side are greater than towards the right side. This happens to the flag on the rope.
What causes the flag to move to the left?
(Variations accepted)
On a position-time graph, what would a downward diagonal line that starts at 30m, 15min and stops at 0m, 45min represent?
Options: Object reached the destination, Object returned to starting point, Object was not moving
Object returned to starting point
Examples of this type of force are applied, normal, and friction.
What are contact forces?
Two ways to increase this type of energy is to increase the speed and/or increase the mass of the object in motion.
What is kinetic energy?
A horse exerts a force of 180N to move a cart forward at 2 m/s2. What is the mass of the cart the horse is moving?
What is 90kg?
This is the average speed of a car that traveled 180 miles in 3 hours.
What is 60mph? (miles per hour)
On a speed-time graph, what does a flat line from point 20mph, 20 min to 20mph, 40 min represent?
Options: Object stopped moving, object moved at a constant speed, object slowed down, object speeds up
Object moved at a constant speed
The direction and magnitude (or strength) are needed to describe this vocabulary word.

In a diving competition, this is one way to quickly increase the athletes' potential energy.
What is to increase the height of the diving board?
