What is the resistance to a change in motion called?

What is inertia

100

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

100

The Unit of force is this.

What is the Newton?

100
This states that an object’s motion will not change unless an unbalanced force acts on the object.
What is Newton's First Law?
100

The unit of distance.

meters, centimeters, kilometers

100

What is the difference between speed and velocity?

direction

200

m/s2

How do you write the unit for acceleration?

200

The acceleration formula is ________velocity minus ________ velocity divided by time. 

Final, initial

200

an object in motion stays in motion unless acted upon by an outside force, is an example of which law?

Newton's first law

200

Which law? F=mxa

Newton's 2nd law

200
This is the tendency of an object to resist a change in its motion.
What is inertia?
200

Give an example of Newton's Third Law?


playing sports, throwing a ball when standing on a skateboard, hitting a wall, sitting in a chairs, walking on the ground,

lots of answers - action/reaction

300

One object pushing on another will always receive a push in return. True or false.

True

300

This property of matter increases with its mass.

What is inertia?

300

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

300
This natural law states that for every action, there is an equal and opposite reaction.
What is Newton’s Third 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?

gravity

300

A train takes 5 seconds to travel 15 meters. What is the train's speed?

3 m/s

400

What causes a ball that has been kicked across the ground to stop?

Friction

400

Objects with more mass need a greater ________ to accelerate

force

400
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?
400

how do you find speed?

What is distance divided by time

400

If someone is pushing a box with 15 Newtons and it accelerates at 5m/s2 , what would the mass of the box be?

3 kg or 3 g

400

If two rocks with different masses are rolling down a hill, will the bigger rock, or smaller rock take more force to stop?

the bigger rock

500

According to Newton’s Second Law, if the force increased but the mass remained the same, what happened?

The objects acceleration increased.

500

dribbling a basketball is an example of which law?

What is Newton's third law

500

A ball bounces away when another ball hits it. Which law does this demonstrate?

Newton's 3rd law.

500

The unit of mass.

What is kilogram?

If you drop two rocks with different masses from the top of a building at the exact same time. Which one will hit first?

They will hit at the same time.
