This occurs when an object changes position relative to a reference point.
What is motion.
100
This includes the speed and direction of an object.
What is velocity.
100
Force is defined as this.
What is a push or pull on an object.
100
This law of motion is also known as the Law of Inertia.
What is Newton's 1st Law of Motion.
100

This is any two masses that exert a pulling force on each other.

What is gravity.

200

These are the 3 variables used to describe motion.

What is time, distance, and speed.

200

What is the common unit for acceleration?

What is m/s^2

200

Net force will equal zero when...

What is forces acting on the object are equal, balanced

200
The tendency of an object to resist any change in its motion.
What is inertia. (Which is a property of matter.)
200
Gravity depends on the _____ and _____ between two objects.
What is mass and distance.
300

A kid is riding in a wagon, what could you choose as a reference point to make it seem like the kid is NOT in motion?

The wagon...

300

These are the four different kinds of friction

Static, Rolling, Sliding, Fluid

300
Force is dependent on these 2 factors.
What is mass and acceleration. (F=m x a)
300

Newton's 3rd law states...

What is for every action there is an equal (in strength) and opposite (in direction) reaction.

300

The difference between weight and mass

Mass - the matter that makes up an object

Weight - The gravity acting upon the matter of an object

What is 12 km/hr.
400

What is the difference between balanced forces and action reaction forces?

Balanced - two forces acting on 1 object

Action/Reaction - Forces acting upon two different objects

400

The type of friction in which 2 surfaces are not moving past each other

What is static friction.

400

It takes less force to move a ping pong ball than a bowling ball. Which of Newton's Laws is this an example of?

What is Newton's 2nd Law of Motion.

400

Solve the average speed: a care drove 3 km in 1 hr, 50 km in 1 hr and 211 km in 2 hr

66km/hr

What is 360 mi/hr.
500

What is the acceleration of an object that has an initial velocity of 15 m/s and a final velocity of 3 m/s over 4 s? Is this acceleration positive or negative?

What is -3 m/s^2, acceleration is negative.

500

In ice skating this type of friction is observed.

What is sliding friction.

500
In order for a 12 pound bowling ball to travel with the same acceleration as an 8 pound bowling ball what needs to occur?
What is a greater force must be applied.
500
The Moon has a greater effect on tides than the Sun because it has a greater ____ pull due to the Moon's ____ from the Earth.
What is the gravitational pull; distance.
