We call the resistance to a change in motion this.

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

When billiard balls collide, this is always conserved.

What is momentum?

100

What is the difference between speed and velocity?

direction

200

The unit for acceleration is written as...

What is m/s2?

200

The Moon orbits the Earth in a nearly circular orbit. The Earth's gravitational pull on the Moon is called this.

What is Centripetal Force?

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

This law states F=ma.

What is Newton's 2nd law?

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

A cat is sitting on a windowsill. What is the action force and what is the reaction force?


Action - cat sitting on the windowsill.

Reaction - windowsill pushing back against the cat.

300

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

True

300

 A ball hitting a bat and a bat hitting a ball is an example of this.

What is a force pair?

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?
300

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

What is 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

This is the formula for speed.

What is distance divided by time? (v=d/t)

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

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

An archer shoots an arrow towards a target. Name one force that will affect the arrow's movement.

Air resistance will slow the arrow; gravity will cause the arrow to move towards the ground; the arrow will stop when it strikes an object or hits the ground; the unbalanced force of friction will act opposite to the motion of the arrow until the arrow stops.

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

This is the unit of momentum.

What is kg.m/s?

500

Gravity is affected by these two factors.

What is mass and distance?

500

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.
