Force & Motion EOG Review

Key Concept 1:

Force and Motion are related.

Sub Concept 1: A force (push or pull) acts on an object and
affects its motion.

Sub Concept 2: Motion is when an object moves from place
to place as a result of a force (push or pull).

Sub Concept 3: Objects can move at different speeds, over
the same distance in different amounts of time.

Multiple Choice

What is a PUSH or PULL of an object?

• Motion

• Force

• Friction

• Gravity

Multiple Choice

Mrs. Gibson creates an experiment with different heights of ramps to see which height makes a toy car travel farther. What is the variable?

• Size of the car

• Height of the ramp

• Distance the car travels

• Surface of the ramp

Multiple Choice

When playing tug of war and neither side moves, forces are

• mulltiplied

• Unbalanced

• unequal

• Balanced

Key Concept 2:

There are factors that affect the motion of
objects.

Sub Concept 1: Gravity is a force that pulls any
object on or near Earth toward the Earth without
touching it.

Sub Concept 2: Friction is the force that is created
anytime two surfaces move or try to move across each
other.

Sub Concept 3: All matter has mass which affects the
motion of an object.

Multiple Choice

An object's gravity depends on the SIZE of the object.

• True

• False

Multiple Choice

Why are we pulled to Earth's center and NOT the sun's?

• The sun is very LARGE

• The sun is very FAR AWAY

• Earth has a STRONGER GRAVITY than the sun

• Earth ORBITS around the sun

Multiple Choice

What would happen to Earth without the sun's gravity?

• Earth would DRIFT INTO SPACE

• Earth would ORBIT the sun

• Earth would be SMALLER

• Earth would get CLOSER TO OTHER PLANETS

Multiple Choice

The moon’s gravity is weaker than Earth’s because If you went to the moon, you would

• SHRINK and become shorter

• WEIGH LESS than you do on Earth

• FLOAT OFF into space

• Not be able to JUMP

Multiple Choice

Friction is a force that acts in an ___________ direction of movement.

• similar

• opposite

• parallel

• west

Multiple Choice

A type of friction that occurs when air pushes against a moving object causing it to negatively accelerate

• surface area

• air resistance

• descent velocity

• gravity 

Multiple Choice

How does friction affect speed?

• more friction decreases speed

• more friction increases speed

• less friction decreases speed

Multiple Choice

Something with a greater mass requires a(n) _____ force to move it. 

• greater

• lesser

• equal

• opposite

Multiple Choice

Which best describes the speed of a ball as it is thrown straight up into the air and comes back down?

• The ball goes up at a constant speed, stops, then comes down at a constant speed. The ball goes up at a constant speed, stops, then comes down at a constant speed.

• The ball goes up at a constant speed, stops, and increases speed as it comes down

• The ball goes slower and slower as it goes up, stops, and then goes faster and faster as it comes down. e

• The ball goes slower and slower as it goes up, stops, and then comes down at a constant speed.The ball goes slower and slower as it goes up, stops, and then comes down at a constant speed.

Key Concept 3:

Any change in gravity, friction, or mass will
affect the motion of an object.

Sub Concept 1: We can predict the effect of a given
force (push, pull, or friction) on a given object. The
greater the force (push or pull) the greater the
change in motion it produces.

Sub Concept 2: We can predict the effect of a change
in mass on the motion of an object. The greater the
mass of the object being acted on, the less the effect of
the (same) force.

Key Concept 4:

The patterns of an object’s motion in various
situations can be observed and measured.

Sub Concept 1: We can infer the motion of objects in
terms of how far they travel in a certain amount of
time.

Sub Concept 2: We can infer the motion of objects in
terms of the direction in which they travel. (N, S, E,
W, up, down)

Sub Concept 3: It is possible to measure the motion of
an object based on the distance it travels in a
certain amount of time.

Key Concept 5:

Graphs can be used to illustrate the motion of an
object to show a change in position over a period
of time.

Sub Concept 1: A graph can be created using one axis
to represent the distance that an object traveled. The
other axis can be used to represent the period of time
an object traveled.

Sub Concept 2: Both axes (plural of axis) of the graph
demonstrate a relation of distance and time.

Multiple Choice

What does this graph represent? ( *HINT: TWO WORDS)

• constant speed

• no motion

• acceleration

• deceleration

Multiple Choice

The graph below displays the motion of two cars. Which statement best describes the motion of the cars displayed in the graph?

• Car X traveled on a curvier road than Car Y.

• Car X traveled on a straighter road than Car Y.

• Car Y traveled at a constant speed, while Car X did not.

• Car X traveled at a constant speed, while Car Y did not.

Multiple Choice

Speed tells us the rate at which an object _______________.

• races

• falls

• moves

Multiple Choice

What is always plotted on the x-axis?

• Time

• Distance

Multiple Choice

Which best describes what happens on a position over time graph when an object stops moving?

• The position increases, and the time increases.

• The position increases, but the time stays the same.

• The position does not change, but the time increases.

• The position does not change, and the time stays the same.

Multiple Choice

What does a horizontal line on a distance-time graph represent?

• increase in speed

• decrease in speed

• acceleration

• no motion

Multiple Choice

Deceleration graphs start with a steep slope and levels out.

So we would say the the object is going ______________ in the beginning of its trip then slows to a stop.
