Matter Review Force and Motion

One object rubbing against another object produces a force that works against motion is known as friction

• True
• False

An object's speed in a particular direction is 

• force
• inerita
• velocity
• speed

• the momentum of the ball
• the inerita of the ball
• the pull of gravity on the ball

An object is moving at a constant speed. If a balanced force is applied in the opposite direction the object is moving, what will most likely happen?

• The object will slow down and eventually stop moving
• The object will continue moving at a constant speed
• the object will change direction
• the object will speed up

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

What is the difference between mass and weight?

• mass is how much matter is in an object, and weight is the gravitational pull on that object
• mass and weight are the same
• weight affects how much mass is in an object
• weight is determined by how many atoms make up an object

If these boys are pulling with the same amount of force.  What will happen?

• The boy in blue will win.
• They will not move at all.
• The boy in red will win.
• Both will fall down.

• it has greater momentum
• it has greater friction
• it has greater acceleration
