AP Physics 1 Concept Review 1

Question 1

An object is hard to push because it is heavy

Accepted Answer

No. It is hard to push when the F of friction is high

Question 2

The pitch of a tuning fork will change as it “slows down,” or “runs” out of energy

Accepted Answer

false

Question 3

When an object hangs over a pulley and drags another object along, the tension in the string...

Accepted Answer

is the same throughout the string

Question 4

The units for velocity and speed are the same.

Accepted Answer

true

Question 5

Acceleration always occurs in the same direction as an object is moving

Accepted Answer

False

Question 6

If energy is conserved, why are we running out of it?

Accepted Answer

That's not what conservation means in physics

Question 7

There is no gravity in outer space

Accepted Answer

This is absolutely not true. UGM

Question 8

A continuous force is needed for continuous motion

Accepted Answer

No force is needed once the object is in motion

Question 9

The only type of potential energy is gravitational

Accepted Answer

False

Question 10

A force is needed to keep an object moving with a constant speed

Accepted Answer

False

Question 11

An object at rest has no energy

Accepted Answer

false

Question 12

Heavier objects fall faster than lighter ones

Accepted Answer

No, gravity is the same for all objects

Question 13

Batteries have electricity inside them

Accepted Answer

False. The 2 ends just have different potentials so e- move

Question 14

You can be moving in a circle at a constant velocity.

Accepted Answer

False

Question 15

Positively charged objects have gained protons.

Accepted Answer

Absolutely not. Only e- can move. + means a loss of e-

Question 16

If an object is at rest, no forces are acting on the object

Accepted Answer

False

Question 17

When an object hangs over a pulley and drags another object along, the hanging mass ...

Accepted Answer

can be any value above zero, is only overcoming friction

Question 18

Hitting an object harder changes its amplitude

Accepted Answer

true

Question 19

A ball rolling down an incline has what types of energy?

Accepted Answer

Ug, Uk, Ukr

Question 20

When an object hangs over a pulley and drags another object along, there is friction acting ...

Accepted Answer

only on the object on the table

Question 21

A charged object can only attract other charged objects

Accepted Answer

False. A q object can attract an opposite charge or neutral.

Question 22

The motion of an object is always in the direction of the net force applied to the object

Accepted Answer

False. An object could be slowing down.

Question 23

The terms “energy” and “power” are interchangeable

Accepted Answer

false

Question 24

Everything that moves will eventually come to a stop.

Accepted Answer

No, Newton's first law makes this plain

Question 25

A net force is needed to produce a change in velocity.

Accepted Answer

True

Question 26

You can be accelerating and also moving at a constant speed.

Accepted Answer

True

Question 27

Hitting an object harder changes its pitch

Accepted Answer

False

Question 28

Frequency and pitch are the same thing for sound.

Accepted Answer

True

Question 29

If an object has a speed of zero, even instantaneously, it can still be accelerating

Accepted Answer

true

Question 30

The electric company sells power.

Accepted Answer

false

Question 31

The terms “energy” and “force” are interchangeable

Accepted Answer

False

Question 32

Gravitational forces are stronger than electrostatic forces.

Accepted Answer

No, electrostatic forces are larger & act over smaller d.

Question 33

Doubling the speed of a moving object ... the kinetic energy

Accepted Answer

quadruples

Question 34

When an object hangs over a pulley and drags another object along, the acceleration

Accepted Answer

is the same for both objects
