Because the large semi truck has more inertia than the smaller mini cooper. It has more resistance to change.
Explain why it takes a large semi truck more time to take off from a stoplight than it does a mini cooper.

Two girls are pushing a large box down a hallway. One girl is pressing on the box with a force of 15 Newtons and the other with a force of 25 Newtons. What is the net force being placed on the box?
200
A change in velocity.
Define Acceleration.
300
The force exerted between electrically charged moving particles, creating a field.
Magnetic Force is...
300
Inertia
Describes the resistance of an object to change.

If the clothes line sank with a force of 2 Newtons than when the bird flies away the line will come back up in the opposite direction with a force of 2 Newtons. Newtons Third Law.
Small birds are sitting on a clothes line when a rather large bird comes and lands on the line; causing it to sink with a force of 2 Newtons. Describe what will happen if the large bird flies away.
300
The box will not move; balanced.
If a large box has a force of 28 Newtons being exerted upon it on either side what can we assume about the movement of the box? Is this illustrating balanced or unbalanced forces?
300
Rolling Friction
Friction involving a moving sphere is called.
400
A force that resists motion between two surfaces that are pressed together.
What is friction?
400
30 Newtons
What force is being applied to a 15kg box that is accelerating at 2.0 m/sec/sec?
400
Use Newton's First law and knowledge of inertia to defend answer.
Why are seatbelts useful? Provide an explanation.
400
50 Newtons, The wall does not move therefore the forces are balanced.
If a man presses on a wall with a force of 50 Newtons. What force is the wall exerting on the man? How do you know?
400
Fluid Friction
What type of friction was illustrated by the parachute in the force and action lab? Explain how you know.
500
Force is a push or a pull that causes an object to move, stop moving or change direction.
Define force.
500
For every action their is an equal and opposite reaction.
State Newton's Third Law of Motion.
500
Since the Earth has a larger gravitation pull than the moon there is a larger force of attraction pulling us down; this explain why we weigh more on Earth than on the moon. Mass is a measure of matter contained within a body and weight is mass plus the pu
Explain why your weight is different on Earth than it is on the moon; and why your mass would be the same in both locations.
500
The total force on the box is 10N. The direction the box will move is to the left. Ms. Thomasson placed a larger force on the box.
If Ms. Thomasson is pushing on a box with a force of 15N to the left and Ms. Clayton is pushing on the opposite side of the box with a force of 5N to the right what is the total amount of force being put on the box? What direction will the box move?
