Question 1

1.

What is the definition of mass? Check all that apply.

push or pull on an object with mass that causes it to change velocity (to accelerate)

measured in grams or kilograms

a vector measurement of the rate and direction of motion

the amount of matter an object

any action that tends to maintain or alter the motion of a body

a measure of the number of atoms in an object combined with the density of those atoms

time rate of change of position of a body in a specified direction

measured in meters per second (m/s)

cause of motion or change, measured in Newtons

the quantity of motion of a moving body; the more it has, the harder it is to stop

Question 2

2.

a measure of the number of atoms in an object combined with the density of those atoms

time rate of change of position of a body in a specified direction

measured in meters per second (m/s)

cause of motion or change, measured in Newtons

the quantity of motion of a moving body; the more it has, the harder it is to stop

Question 3

3.

What is the definition of momentum? Check all that apply.

push or pull on an object with mass that causes it to change velocity (to accelerate)

measured in grams or kilograms

a vector measurement of the rate and direction of motion

the amount of matter an object

any action that tends to maintain or alter the motion of a body

a measure of the number of atoms in an object combined with the density of those atoms

time rate of change of position of a body in a specified direction

measured in meters per second (m/s)

cause of motion or change, measured in Newtons

the quantity of motion of a moving body; the more it has, the harder it is to stop

Question 4

4.

What is momentum, and how is it calculated?

Momentum is the energy an object possesses and is calculated by adding mass and velocity

Momentum is the force applied over time and is calculated by multiplying mass and velocity.

Momentum is the product of an object's mass and velocity, calculated by the formula p=mv

Momentum is the speed of an object and is calculated by dividing mass by velocity.

Question 5

5.

Using the equation for momentum, what is the momentum of a bird with a mass of 0.18 kg that is flying at 15 m/s?
