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
