Forces and Motion: Lesson 3 & 4 Review

A measure of how much matter an object has is ....

• weight
• gravity
• mass
• volume

What is the definition of weight?

• measure of the force of gravity on an object

• multiplying mass by acceleration

• the amount of matter in an object
• the size of an object

Why do all of the planets orbit the sun rather than Earth?

• the sun has more mass

• the sun is a star

• the Earth is heavier

• the sun is in the middle of the milky way

As an object's mass increases, its gravitational pull will ____________.

• decrease
• increase
• stay the same
• get weaker

If an object has more mass, then it will

• weigh more.
• weigh less.
• weigh the same as an object with less mass.
• always have more volume than an object with less mass.

Why would you weigh less on the moon compared to Earth?

• less air
• less sunlight
• more gravitational pull
• less gravitational pull

As mass increases, what happens to gravitational force?

• increases
• decreases
• stays the same
• i don't know

What best describes the mass and weight of a person as they move around the universe?

• mass and weight changes
• Mass and weight stays constant
• weight remains constant, mass changes
• Mass stays constant, weight changes
