If you hit a wall with 100 N, what happens?
A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them. Which of Newton's Laws is occurring?
A person’s body is thrown outward as a car rounds a curve on a highway.
Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction.
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Earthquakes, faults, and rift valleys are the result of movement in the crust. What type of movement causes these movements in the earth's plates?
Sitting at the top of a steep hill on a roller coaster (not moving) is an example of:
Refer to the force diagram to the left for question 10-12.
Calculate the net force (Fnet) acting on the object.
Adam is visiting the Grand Canyon with his family. Despite repeated warnings from a park ranger, Adam throws a 0.85 kg (8.3 N) rock off a cliff. Midway through the rock’s fall, the air resistance (pushing upward) on the rock is 4.1 N.
Calculate the net force acting on the rock.
In what direction is the net force applied?
Calculate the acceleration of the object.
In what direction is the net force acting on the rock?
