What is the resistance to a change in motion called?
What is inertia
If something with a mass of 40 kg, is pushed with a force of 120N, what is the acceleration of the object?
3 m/s2
The Unit of force is this.
What is the Newton?
This states that an object’s motion will not change unless a force acts on the object.
What is Newton's First Law?
m/s2
How do you write the unit for acceleration?
The acceleration formula is ________velocity minus ________ velocity divided by time.
Final, initial
an object in motion stays in motion unless acted upon by an outside force, is an example of which law?
Newton's first law
Which law? F=mxa
Newton's 2nd law
One object pushing on another will always receive a push in return. True or false.
True
This is the tendency of an object to resist a change in its motion.
What is inertia?
As the fuel burns in a rocket and gases push against the rocket, moving it upward this explains which of Newtons laws.
Newton's Third Law
What causes a ball that has been kicked across the ground to stop?
Friction
Objects with more mass need a greater ________ to accelerate
force
how do you find velocity?
What is distance divided by time
According to Newton’s Second Law, if the force increased but the mass remained the same, what happened?
The objects acceleration increased.
