Inclined Plane Notes | Honors Physics

What is the "x" component of the gravitational force?

• mg

What is the "y" component of the gravitational force?

• mg

Which of the following is equal in magnitude to the Normal Force?

• (M1)(g)sin28⁰
• (M1)(g)cos28⁰
• (M2)(g)sin28⁰
• (M2)(g)cos28⁰

If an object is at rest on an inclined plane, which of the following forces is greatest?

• Normal Force
• Friction
• Weight
• Both Normal Force and Weight are equal, so they both are the greatest.

What is the x-component of force if the mass of the box is 42kg and the angle is 37º?

• 329 N

• 248 N

• 212 N

• 350 N

What is the acceleration of a 42 kg box on a 37° angle if the force of kinetic friction is 57 N?

• 4.5 m/s²

• 6.5 m/s²

• 1.3 m/s²

• 6 m/s²

A box of weight 150 N is placed on an inclined plane. The component of the box’s weight acting along the plane is W’.

• 155.29 N

• 144.89 N

• 579.56 N

• 38.82 N
