Newton's Laws
A soccer ball remains at rest until a player kicks iit. Which law explains this change?
What is Newton's 1st Law: Inertia
A moving cart hits a stationary cart, causing the stationary cart to move. What interaction caused its motion to change?
What is the moving cart transfers force and energy to the stationary cart.
A book rests on a table. Name the two main vertical forces acting on the book.
An object has zero net force. Are the forces balanced or unbalanced?
What is balanced?
A 4 kg cart accelerates at 3 m/s2. What net forces acts on it? Hint: Force has units of Newtons
What is 12N?
A moving skateboarder hits a wall and stops. Name one design feature that could reduce injury in a similar collision.
What is padding, a helmet, or another impact absorbing feature
A box has a 12 N force to the right and a 12 N force to the left. What is the net forces?
What is 0 N net forces?
A book rests on a table. Are the book's weight and the table's normal forces a Newton's Third Law Pair?
A student pushes a wall, and the wall pushes back. Which law explains this interaction?
What is Newton's 3rd Law: For every action there is an equal and opposite reaction.
During a collision, a ball is struck and transfers all of its energy and force to another object, causing the ball to stop moving. What force causes the object to stop?
What is friction?
A 20 N force pulls a box to the right while friction acts with 5 N to the left. What is the direction of the motion and the net force?
What is 15 N to the right?
A cart experiences 15 N right and 5 N left. Is the net force balanced or unbalanced? Calculate the net force.
What is Unbalanced; net force = 10 N to the right?
Two carts have the same mass. One receives twice the net force. How do their accelerations compare?
What is The cart receiving twice the force has twice the acceleration
What is gravity cause the objects to hit the ground at the same time?
A 10 N Force acts at an angle above the horizontal ground. Given sin(theta) = 3/5. Find the horizontal component of force. Hint: Force = mass x acceleration x sin(theta)
What is 8 N in the x direction?
A swimmer pushes water backward. What force does the water exert on the swimmer, and which law explains this?
What is The water pushes the swimmer forward. Newton’s Third Law?
A 6kg cart experiences a net force of 18 N. Calculate its acceleration and identify the law used.
What is Newton's 2nd Law?
What is add cushioning or shock absorption, repeat controlled drop and vibration tests and compare damage?
A 4 kg box rests on a horizontal floor. Use g = 10 m/s2 . A 10 N horizontal force pulls right while friction is 10 N left. Identify the force pairs and the net force.
What is the Force to the pulling left and friction pulling right and 0 N net force on the system?
A spaceship reaches escape velocity and reaches the upper atmosphere. Explain the force pairs observed.
What is 1 force is from the gas from the spaceship is pushing down and the space ship is pushing up into the atomspheres.
