100
One example of newton's third law
when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
100
What is the definition of force
The push or pull on an object with mass causes it to change its velocity.

one example of newtons first law
The motion of a ball falling down through the atmosphere
200
How do you explain Newton's second law of motion
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.
200
what is an example of newtons third law
When a ball hit the ground or a wall the ball apply a force on the wall or on the ground.
200
What is the definition of Gravity.
the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
200

300
What is the formula for Newton's second law?
300
why is "Pulling an elastic band" an newtons third law
it automatically returns to its original position
300
What is the definition of Unbalanced force
To have unbalanced forces means that the force applied in one direction is greater than the force applied in the opposite direction.
300

400
How does Newton's second law work?
when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate
400
What is Newton's third law formula?

Sir Isaac Newton
500
why is this picture newtons first law because is it acted upon a force
every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
500
why is this picture the newtons second law
acceleration (gaining speed) happens when a force acts on a mass (object).
500
why is this photo newtons third law
If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A
500
What is the definition of Friction
the resistance that one surface or object encounters when moving over another.
500
Why is unbalanced force important?
change the speed or direction of an object that is already in motion.
