Question 7 (1 point) Which list contains only vector quantities? a) velocity, acceleration, force Ob) mass, force, displacement Od time, velocity, acceleration Odl acceleration, velocity, distace power, energy, time dicemente density
The energy of motion is called: Kinetic energy. potential energy, inertial energy. Power. In an inelastic collision: momentum is conserved. kinetic energy is conserved, both (a) and (b). If the velocity of a moving object is doubled and its mass is cut in half, the kinetic energy of the object is; remains the same, doubled quadrupled, cut in half. When the net work done on an object is speed of the object is me on an object is zero; the...
Momentum and kinetic energy are both calculated from the mass and velocity of an object. If mass is conserved during a collision, explain how momentum may be conserved but not kinetic energy.
Question2 Answer the followings, carry 25 points L. State whether following properties are a vector or a scalari? Kinetic energy: Potential energy: Work done: Torque: Pressure: Displacement: Velocity: Momentum: Impulse: Force: Distance Speed: Angular momentum: Angular acceleration: 2. Given the situation as shown in the figure. The hollow sphere is rolling down an inclined plane! Mass of the sphere is M, radius is R and vertical height is H. V is the linear velocity of the center of mass, loe...
Question 10 (1 point) Which list contains only vector quantities? a) displacement, velocity, density b) time, velocity, acceleration c) acceleration, velocity, distance d) power, energy, time e) displacement, velocity, acceleration f) acceleration, force, distance g) mass, force, displacement Question 11 (1 point) Bob is in a helicopter, hovering over Tallula's house. He throws a bowling ball straight down with a speed of 6.81 m/s, hoping to make a hole in Tallula's roof. Unfortunately, he misses, and the ball lands in...
V If two particles of different masses have equal kinetic energy they also have equal momentum. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. If the momentum of a single particle is zero, its kinetic energy may not be zero. The linear momentum of an object is proportional to the mass of the object. A large force always produces a larger impulse on a body than a smaller force. If the kinetic energy of a...
