What are the 3 ways you can change torque?
You can change torque by adjusting the force applied, changing the distance between the force and the pivot point, or altering the angle at which the force is applied relative to the pivot point.
Is it true that frictional force on a sliding body on a plane is always directed at the angle of friction to the normal?
The frictional force on a sliding body on a plane will be acting parallel to the plane against the motion of the body. But the magnitude of the (kinetic) friction force is proportional to the weight component normal to the plane. The weight component parallel to the plane is the force that tends to slide the body down the inclined plane. When the sliding body has acquire steady velocity, the friction force is equal to the body's sliding force.
What must be applied to an object to change its direction?
A force must be applied to an object in order to change its direction. By exerting a force at an angle to the object's initial direction of motion, the object will change its path and move in a different direction.
How would the force of kinetic friction change if you increase the angle of the track?
As the angle of the track increases, the force of kinetic friction also increases. This is because the component of the gravitational force acting parallel to the track increases, leading to a greater resistance against the motion of the object.
What change the direction of applied force?
The direction of an applied force can be changed by using a lever, pulley, or a combination of gears. By altering the angle or position of these mechanical devices, the applied force can be redirected to achieve the desired result.

When a ramp is at a angle of 10.5 degrees what will be the applied force?
The applied force will depend on the required force, and the angle to the ramp (or the horizontal) at which the force is applied.
What change the direction of applied force?
The direction of an applied force can be changed by using a lever, pulley, or a combination of gears. By altering the angle or position of these mechanical devices, the applied force can be redirected to achieve the desired result.
How does an angle affect friction?
An angle can affect friction by changing the normal force acting on an object. When an object is on an inclined plane, the normal force is reduced, which can affect the frictional force acting on the object. As the angle increases, the component of gravitational force acting parallel to the surface also increases, which can increase the frictional force to prevent the object from sliding.
Why does applied torque not change at 90 degrees?
At 90 degrees, the applied torque remains constant because torque is defined as the product of the force and the distance from the pivot point, multiplied by the sine of the angle between the force vector and the lever arm. At 90 degrees, the sine of the angle is 1, meaning that the entire force contributes to the torque. Therefore, while the angle changes, the magnitude of the torque does not, as it is maximized when the force is applied perpendicular to the lever arm.
A 2.0 kg wood box slides down a vertical wood wall while you push on it at a 45 angle. What is the force applied to slide the box down at a constant speed?
The force applied to slide the box down at a constant speed is equal to the force of kinetic friction acting against the box. This force is given by the equation: friction force = coefficient of kinetic friction * normal force. Since the box is sliding down the wall, the normal force is equal to the weight of the box. Therefore, the force applied is equal to the coefficient of kinetic friction * weight of the box.
How does the change in the angle of incidence affect the angle of reflection?
The angle of reflection is equal to the angle of incidence. When the angle of incidence changes, the angle of reflection will also change accordingly, maintaining the law of reflection.
Which situation below describes that the law of reflection is being applied?
When light rays hit a mirror and are reflected back at the same angle at which they hit the mirror, the law of reflection is being applied. This law states that the angle of incidence is equal to the angle of reflection.
What is the expression for kinetic energy in spherical coordinates?
The expression for kinetic energy in spherical coordinates is given by: KE 0.5 m (r2) ('2 sin2() '2) where KE is the kinetic energy, m is the mass of the object, r is the radial distance, is the polar angle, is the azimuthal angle, and ' and ' are the angular velocities in the respective directions.
