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.

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia
• Newton's second law, the law of acceleration
• Newton's third law, the law of action reaction 
• The law of universal gravitation

A squirrel sits on the ground and eats a donut. We know the forces on him must be balanced because...

• Forces are always balanced

• the squirrel is not accelerating

• squirrels are projectiles

• he's eating a donut

A baseball player hits a ball with a bat. If the force on the ball is increased, what happens to the acceleration of the ball, assuming the mass remains constant?

• The acceleration decreases.

• The acceleration remains the same.

• The acceleration increases.

• The acceleration becomes zero.

The girl on the sled will remain in motion unless

• her motion is changed by magnetic forces.

• she is stopped by an outside force.

• she accelerates at a constant speed.

• the force of friction forcer her to move faster.
