Forces & Motion

What happens when the same amount of force is applied to both sides of the box?

• the forces are unbalanced and will move to the left

• the forces are balanced and will move to the right

• the forces are unbalanced and will remain at rest

• the forces are balanced and will remain at rest

What is force?

• A push exerted on an object
• A push or pull exerted on an object
• A pull exerted on an object
• Nothing

The SI Unit of force is

• Pascal
• Meter/second
• Newton
• kg

8 N to the left , and 4 N to the right. Find the net force. Is this balanced?

• 12 N Right;  No
• 4 N Left;  No
• 12 N Right;  Yes
• 4 N Left;  Yes

Which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force

How do you know if and object has balanced force?

• It only has one force
• it's moving
• It has equal forces on all sides
• it's staying still

A direct force is from...

• objects physically touching

• far apart objects

• not touching object

• always a pull

A indirect force is between...

• two objects that aren't touching

• two objects that are touching

• the ground and wheels

• you and me

The three examples pictured are of

• Non-contact Forces

• Contact Forces

You are pulled to the surface of the earth due to the force of _________________

• gravity

• friction

• normal force

• contact force
