Newtons Laws 1
This is the Law of Inertia
What is Newtons First law
What force stops a ball that is thrown in the air from flying up forever?
What is Gravity
The unit of force in the SI system.
What is a newton?
This states that an object’s motion will not change unless an unbalanced force acts on the object.
What is Newton's First Law or Law of Inertia
The unit of acceleration is this.
What is m/s2
According to Newton’s Second Law, increasing the force applied to a mass has this result.
What is increases acceleration of the object
A box is being pushed to the right across the floor. What force is acting towards the left?
What is friction
Newton's third law states...
What is any action force has an equal and opposite reaction force?
Example of a non-contact force?
What is gravity or magnetic force or electric force
Mass has this unit.
What is kg, kilogram
A 1kg object accelerates at a rate of 10m/s2. Calculate the net force of the object.
What is 10N
A bowling ball collides with a set of bowling pins (at rest) with a force of 15N. What is the force the pins exert on the bowling ball?
What is 15N
A car and a train are going the same speed. The car is easier to stop because.
What is it has less mass and less inertia?
This occurs whenever an object is acted upon by an unbalanced force.
What is acceleration, or change in motion
This is required to overcome an object’s inertia.
What is an unbalanced force or net force
An object at rest has this velocity.
What is Zero
If you want to increase the acceleration of a baseball when you throw it, what must you increase to make this happen?
Force
Newtons law of action and Reaction
What is 3rd law?
Newton's second law's equation
What is Fnet = m x a
A force of 20N acts upon a 5 kg block. Calculate the acceleration of the object.
What is 4m/s2
Two ice skaters push off of each other and they both glide in opposite directions. Which of Newton's Laws does this best represent?
What is Newton's 3rd Law
The three accelerators in your automobile's control system
What is gas, brake and steering wheel?
The product of mass and velocity
What is momentum?
If a ball is hit with a force 49 Newtons and has an acceleration of 7 m/s2, what is the ball's mass?
What is 7 kg?
How fast something(an object) is moving in a given direction.
What is velocity?
