Science Ch 8

What is Force?

• A push or pull motion

• A superpower

• Something that happens without your consent

• A motion that puts something in motion

What is friction?

• A force of attraction between two objects

• A force that opposes motion

• A force that shoots upwards

• A force that controls you

Force is measured with the unit Newtons

• True

• False

• Sometimes

What is Gravity?

• A push or pull motion

• A force that pushes you down

• A force that opposes motion

• A force of attraction between two objects

If the mass of the object increases, does the force of gravity on it increase or decrease?

• Increase

• Decrease

• Stay the Same

What is a balanced force?

• Forces on an object that are equal in size and opposite in direction

• Forces on an object that are not equal in size and opposite in direction

• Forces on an object that are equal in size and going the same direction

• Forces on an object that are not equal in size and going in the same direction

What is an unbalanced force?

• Force that cancels each other out

• Force that pulls you down

• Forces that cause a change in motion

• Force that opposes motion

True or False: A force does not need to overcome the force of friction before an object will move

• True

• False

• Depends

A measure of the force that gravity exerts on an object. So, for example, this would be much more on Earth than on the Moon.

• Mass

• Acceleration

• Weight

• Force

If a bicyclist is biking on a bumpy road, what forces are acting upon them?

Pick all that are true.

• Air Resistance

• Acceleration

• Gravity

• Friction
