kinetic energy
This one of Newton's Laws states that for every action there is an equal opposite reaction. (Number of Law)
What is Newton's Third Law?
A car driving down the highway at 65 mph has ________ forces acting on it.
What are balanced forces?
On a distance vs time graph, this is happening to an object when their is a horizontal line with no slope.
What is the object is not moving?
When a person applies a certain force with their muscles in order to move the bar complete a bench press follows this one of Newton's Laws
What is Newton's Second Law of Motion?
The change in speed or direction is called this.
What is acceleration?
This one of Newton's Laws states that an object in motion will stay in motion and an object at rest will stay at rest unless acted on by an outside force (Number of Law, Other Name of Law).
What is Newton's First Law, Law of Inertia
A car turning left into a parking lot at 15 mph has ___________ forces acting on it.
What are unbalanced forces?
On a distance vs time graph, this is happening to the object when the line has a negative slope.
What is returning back to the starting point with a constant speed?
On a speed vs time graph, a line with a negative slope shows that the object is moving like this.
What is slowing down?
This is the total of all the forces acting on an object at a time.
What is a net force?
This one of Newton's Laws states that an object with a larger mass will require a larger force to accelerate the object. (Number of Law, Other Name of Law)
What is Newton's Second Law, F=ma
This force opposes motion
What is friction?

What is 9.3 m/s?
The world's heaviest squat is 500 kg. The weightlifter lifted the weights with an acceleration of .33 m/s^2. The weightlifter lifted the weights with this amount of force.
What is 165 N?
m/s^2 is the unit of this?
What is acceleration?
A running back who is refusing to be tackled to the ground while running in a straight line to the endzone is an illustration of this Newton's Law of Motion.
Newton's First Law, Law of Inertia
This force opposes gravity when you are standing on an solid object.
What is the normal force?
What is accelerating?
Unbalanced Forces always act in this direction.
What is the direction of the larger force?
The resistance to the change in motion of an object.
What is inertia?
A rocket being propelled into space from the launchpad follows this one of Newton's Laws.
Action-Reaction / Newton's Third Law
Describe the net force of a car that is turning right into a parking spot at 10 miles an hour. (consider what type of forces are acting on the object)
What is greater than 0?
On a speed v time graph, this motion is occuring when the line crosses over the x-axis.
What is no motion
If you double the mass of an object and apply the same force, this happens to the acceleration of the object.
What is, the object's acceleration is decreased by half?
