1 Name
The upward support force provided by a surface.
What is the normal force?
This scientist developed the three laws of motion.
Who is Isaac Newton?
The law that states an object at rest stays at rest unless acted upon by an unbalanced force.
What is Newton's First Law?
Forces that cause an object to accelerate.
What are unbalanced forces?
If a soccer ball is kicked and begins moving, the kick provided this type of force.
What is an unbalanced force?
The SI unit used to measure force.
What is a Newton (N)?
This equation is used to calculate force when mass and acceleration are known.
What is F = ma?
A diagram that shows all the forces acting on an object.
What is a free body diagram?
The mass of an object that accelerates at 5 m/s² when a force of 25 N is applied.
What is 5 kg?
The force that slows down a moving bicycle when the brakes are applied.
What is friction?
This force pulls all objects toward the center of the Earth.
What is gravity?
The law stating that for every action there is an equal and opposite reaction.
What is Newton's Third Law?
In a free body diagram, this feature indicates the strength of a force.
What is the length of the arrow (magnitude)?
The net force on an object if 20 N acts right and 15 N acts left.
What is 5 N to the right?
The acceleration of an object if a 12 N force acts on a 4 kg object.
What is 3 m/s²?
A force that opposes motion between two surfaces rubbing together.
What is friction?
The tendency of an object to resist changes in its motion.
What is inertia?
Name the two main vertical forces acting on a golf ball resting on a tee.
What are gravity and the normal force?
The state of motion of an object experiencing balanced forces.
What is remaining at rest or moving at a constant speed?
A passenger continuing forward when a car suddenly stops is demonstrating this concept.
What is inertia?
Forces that are equal and opposite, resulting in no change in motion.
What are balanced forces?
The force that acts when you pull a wagon with a rope.
What is tension?
A rocket launches because gases are expelled downward, creating this upward force on the rocket.
What is thrust?
The reaction force that allows a swimmer to move forward.
What is the water pushing the swimmer forward?
The action force when a swimmer moves through water.
What is the swimmer pushing the water backward?
