8th Pre test

A push or pull placed on an object is called

• force

• motion

• acceleration

• velocity

What is the equation for Force?

• velocity x motion

• mass x acceleration

• kilograms x mass

• meters / seconds

What are the two factors that affect the force of gravity?

• distance and time

• mass and speed

• mass and distance

What is mass?

• The amount of matter in an object

• The measurement of force placed on an object due to the acceleration of gravity acting on the object's mass

What is weight?

• The amount of matter in an object

• The measurement of force placed on an object due to the acceleration of gravity acting on the object's mass

What is Newton's FIRST law?

• An object that is a rest will remain at rest, and an object in motion will stay in motion unless an outside force acts upon it

• If a force increases, so will mass and acceleration. If mass or acceleration decrease, so will force.

• For every action, there is an equal and opposite reaction

What is Newton's SECOND law?

• For every action there is an equal and opposite reaction

• If force increases, so will mass and acceleration. If mass or acceleration decrease, so will force.

• An object at rest will remain at rest, and an object in motion will stay in motion unless an outside force acts upon it.

What is Newton's THIRD law?

• For every action, there is an equal and opposite reaction

• An object at rest will remain at rest, and an object in motion will stay in motion unless an outside force acts upon it.

• If force increases, so will mass and acceleration. If mass or acceleration decrease, so will force.

Multiplying the object's mass and velocity determines what?

• speed

• momentum

• force

• weight

what is the volume?

• 72
• 27
• 1.5
• 272
