Study Notes
Review for Final Exam - Fall Semester
- Concurrent Forces: Two forces of 40 Newtons and X Newtons have a resultant of 100 Newtons. Possible values of X include 80 Newtons.
- Vector Quantities and Units: Weight is measured in kilograms, speed in meters per second (m/s), and velocity also in m/s.
- Paper Clip Mass: A paper clip has a mass of approximately 1 x 10⁻³ kg.
- Weight of Object: A 2.00-kilogram object weighs 19.6 N on Earth.
- Gravitational Force Magnitude: If the mass of two objects is doubled, the gravitational force between them increases to 80 N, starting from an initial magnitude of 20 N.
- Amusement Park Ride Speed: A student on an amusement park ride moving in a circular path with a radius of 3.5 meters once every 8.9 seconds has an average speed of 1.2 m/s.
- Hiker's Total Distance: A hiker traveling 1.0 km south, 3.0 km west, and 3.0 km north travels a total distance of 7.0 km.
- Inclined Plane Friction: Increasing the angle of an inclined plane increases the coefficient of kinetic friction between the block and the surface.
- Elevator Force: A 750-newton person in a downward-accelerating elevator experiences an upward force less than 750 N from the floor.
- Force and Horizontal Component: As the angle between a force and the ground decreases from 60° to 30°, the vertical component of the force increases.
- Car Deceleration Direction: A car slowing down while moving south has a southward acceleration.
- Lab Cart Acceleration Magnitude: A 1.5-kilogram lab cart accelerates uniformly from rest to 2.0 m/s in 0.50 s has an acceleration magnitude of 3.0 N.
- Gravitational Force and Mass: Increasing the mass of a body increases its gravitational force of attraction to Earth.
- Centripetal Acceleration: Doubling the velocity of a ball doubles its centripetal acceleration.
- Gravitational Force Between Soccer Balls: Two 0.425-kilogram soccer balls separated by 0.500 m experience a gravitational force of approximately 5.67 x 10⁻¹¹ N.
- Perpendicular Displacement Components: A 20-meter displacement vector can have perpendicular components with magnitudes of 12 m and 16 m.
- Constant Velocity Friction: A horizontal force of 20 N is needed to move a 5 kg box at a constant velocity of 3.0 m/s.
- Car Acceleration: A car initially traveling east at 16.0 m/s and slowing down to 6.0 m/s in 4.0 seconds has an acceleration of 2.5 m/s² west.
- Horizontal Force Needed for Constant Velocity: A 500-Newton object moving horizontally at a constant velocity of 2.0 m/s requires a 50 N horizontal force.
- Vertical Component of a Force: A 100-Newton force applied at a 30° angle from the horizontal has a vertical component of 50.0 N.
- Concurrent Forces Resultant: The resultant force has the largest magnitude when the angle between the forces is zero.
- Acceleration from Force Application: Applying 10 N of force to a 4.0-kilogram mass causes an acceleration of 2.5 m/s².
- Centripetal Acceleration Calculation: A 5.0 kg object moving in a circle of radius 2.0 meters with an acceleration of 40 N has a speed of 4.0 m/s.
- Displacement Magnitude: A person walking 17 m east and then 17 m south has a displacement magnitude of 24 m.
- Interplanetary Force of Attraction: The gravitational force between Uranus and Neptune at a distance of 1.63 × 10¹² m is approximately 5.971x10¹⁷ N
- Net Force on a Box: A constant 15 N force applied to a 2.5 kg box across a rough surface at 2.0 m/s² acceleration results in a 5 N net force.
- Friction on the Box: The force of friction on a box being pushed with a constant force of 15 N and a constant acceleration of 2.0 m/s² is 5 N.
True/False Concept Review (General Physics Concepts)
- Vectors vs. Scalars: Vectors have magnitude and direction, scalars only have magnitude.
- Distance and Displacement: Displacement (vector) is the change in position, distance (scalar) is the total path covered.
- Velocity and Speed: Velocity is a vector, speed a scalar; both relate to rate of motion.
- Acceleration: A vector quantity depicting change of velocity over time
- Inertia: A property of matter resisting changes in motion—more massive objects have greater inertia. Mass is a quantity not Force.
- Mass and Weight: Mass is a property of matter, weight is the force of gravity on an object. Mass doesn't change, weight does according to location
- Force: A push or pull that causes acceleration, measured in Newtons.
- Balanced Forces: Balanced forces result in no acceleration, unbalanced forces result in acceleration.
- Objects Moving in Circles: A circular motion object experiences a net force directed toward the center
- Gravitational Force: The force of attraction between massive bodies; directly proportional to mass. Inversley proportional to the square of separating distance.
