TRUE OR FALSE: Static Friction is the type of friction when the object is not moving.

TRUE OR FALSE: Static equilibrium happens when the object is at constant velocity

TRUE OR FALSE: Energy efficiency is defined as the total energy input divided by the total energy output.

TRUE OR FALSE: When the body moves in a circular path at varying speeds, the motion is in non-uniform circular motion.

TRUE OR FALSE: Angular Velocity is analogous to linear velocity wherein it gives the displacement of the angle per unit of time

TRUE OR FALSE: The points farther from the axis of rotation have higher average linear velocity.

TRUE OR FALSE: Hooke's Law states that the forces applied to an object are proportional to the elongation and compression.

TRUE OR FALSE: If the object exceeds its elastic limit it can freely go back to its original shape.

TRUE OR FALSE: A solid sphere, a solid cylinder, and a hollow pipe all have equal masses and radii. If the three of them are released simultaneously in an inclined plane and do not slip, we can say that the solid sphere will reach the bottom first.

The mathematician, engineer, scientist and knight who was behind the initial idea of gravitation

It is the rotational equivalence of linear momentum

If both the force applied (F) and the elongation (x) is in negative sign the spring is _______________.

It is the state of a rigid body where a solid object is not moving because its influences are balanced

The influences that affect static equilibrium are _______________ and _________________.

It is the measure of the force that can cause an object to rotate about an axis

The value of the universal gravitational constant is ___________________.

The unit for angular momentum is _____________.

This law states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of the two masses and inversely proportional to the square of the distances between their centers

This law states that the total angular momentum of a rotating object is constant when the net external torque acting on it is zero

[10points] A 100-kg object is suspended by two cables at a different angle from the horizontal. T1 is at 45 degrees and T2 is at 35 degrees. Find the tension in each cable.

[5 points] Determine the gravitational force between Earth and Jupiter if Earth is 591 million km away from the planet Jupiter. Earth's mass is 5.972x10^24 kg and Jupiter's mass is 1.90x10^27 kg.

[5 points] A figure skater spins on an icy surface. Her moment of inertia is 3.0 kg-m² when her arms are stretched away from her and drops to 2.2 kg-m² when her arms are close to her chest. If she makes three revolutions per second (rps) when her arms are stretched, how many rps will she make when she puts her arms to her chest?

[5 points] An airliner arrives at the terminal and the engines are shut off. The rotor of one of the engines has an initial clockwise angular speed of 2000 rad/s. The engines rotation slows with an angular acceleration of magnitude 80 rad/s². Determine the angular speed after 10 s.
