#22 Newton's Laws

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

• Motion
• Friction
• Work
• Displacement

Which force produces a change in motion?

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

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.

Speed is equal to 

• Distance/Time
• Time/Distance
• Time x Distance
• Acceleration

Speed is different from velocity because

• Velocity has a direction
• Speed uses Distance /Time
• Velocity doesn't include time
• Velocity doesn't include distance

If you double the mass of an object with the same force apply on it, the acceleration will

• double
• cut in half
• the same
• zero

Which one of Newton’s Laws of Motion best explains why the dishes do not move when the table cloth is removed?

• Newton's 1st Law
• Newton's 2nd Law 
• Newton's 3rd Law 
• Newton's Law of Biology

The resistance of an object to any change in its motion is called ______________________.

• inertia

• friction

• gravity

• weight
