Forces and Motion Post

What is MOVEMENT?

• Inertia
• Force
• Work
• Motion

What happens when one force PULLS an object toward another?

• Friction
• Motion
• Gravity
• Magnetism

What is a force that works AGAINST MOTION?

• Force
• Motion
• Gravity
• Friction

Why is it harder for the boy in Image B to get down the hill?

• Motion
• Friction
• Work
• Displacement

In the image, which of the person and their bikes will get down a hill faster? 

• The boy because he is younger
• The woman because she is stronger
• The boy because he has a greater mass which applies a greater force
• The woman because she has more mass and applies a greater force

How is gravity affected by mass?

• the larger the mass of the object, the greater the gravity
• small objects have no gravity
• gravity is not affected by mass of objects, whether large or small

Which force produces a change in motion?

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

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

Why does a rolling ball stop?

• Gravity
• Friction
• Waterfalls
• Sand
