Newtons Laws
The acceleration includes what two factors.
What is: Distance and time
What is the resistance to a change in motion called?
What is: Inertia
True or False: If something with a mass of 40 kg, is pushed with a force of 120N, the acceleration will be 3 m/s2?
What is: True
This states that an object’s motion will not change unless an unbalanced force acts on the object.
What is: Newton's First Law
IF something is moving at a constant speed, is it balanced or unbalanced?
What is: Balanced
The unit of force is this.
What is: Newton
This is the tendency of an object to resist a change in its motion.
What is: Inertia
Newton's Third Law of Motion states that the action and reaction must be
What is: Equal and opposite
If forces are equaled out, they are _________ forces.
What is: Balanced
an object in motion stays in motion unless acted upon by an outside force, is an example of which law?
What is: Newton's first law
A student lets a toy car roll four times down a ramp that is 1 m long. Each time the student covers the surface of the ramp with a different material. The student measures the time it takes the car to roll down the ramp and records the info. Each trial has a different time. What conclusion can you draw about the ramp?
What is: Different amounts of friction
F = m x a
What is: Newton's 2nd Law
If you put a notecard on a cup, and a penny on top of the notecard and flick the card so the penny falls in the cup, which force is acting on the penny so it falls down?
What is: Gravity
One object pushing on another will always receive a push in return. True or false.
What is: True
This property of matter increases with its mass.
What is:Interia
What happens when a rocket launches to make it an example of Newton's Third Law?
What is: As the fuel burns, gases push against the rocket, moving it upward.
If a box is being pushed with a force of 5 N to the right and also being pushed, in the opposite direction with a force of 12 N, would you add or subtract to find the net force?
What is: Subtract
This natural law states that for every action, there is an equal and opposite reaction.
What is: Newton’s Third Law
If someone is pushing a box with 15 Newtons of force to the right, and another person is pulling the box with 5 N of force, what is the net force?
What is: 20 N to the right
What causes a ball that has been kicked across the ground to stop?
What is: Friction
Objects with more mass are ______ to set in motion.
What is: Harder
A car and a train are going the same speed. The car is easier to stop because of this.
What is: Less mass and less inertia
If two rocks with different masses are rolling down a hill, will the bigger rock, or smaller rock take more force to stop?
What is: The bigger rock
How do you find speed?
What is: Distance / Time
Velocity is the measure of
What is: Speed and direction
According to Newton’s Second Law, if the force increased but the mass remained the same, what happened?
What is: The objects acceleration increased.
dribbling a basketball is an example of which law?
What is: Newton's third law
A ball bounces away when another ball hits it. Which law does this demonstrate?
What is: Newton's 3rd law
The attractive force that exists between all objects that have mass?
What is: Gravity
The standard unit of mass is this.
What is: Kilogram
