Force & Motion

What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

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

• Motion
• Friction
• Work
• Displacement

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.

_______________ is how fast an object changes over time. 

• speed
• velocity
• momentum
• acceleration

When you tell the direction and speed of an object, you give its __________________.

• motion

• velocity

• acceleration

• mass

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

Objects that are changing their speed or their direction 

• force
• energy
• acceleration
• friction

a force that causes a change in motion of an object

• friction
• balanced force
• unbalanced force
• force

two or more forces act upon an object and cancel each other out causing no change in motion

• friction

• balanced force

• unbalanced force

• force

__________ is an objects ability to resist change in motion

• inertia

• kinetic energy

• potential energy

• force
