OBJECTIVES: students should be able to ...

B: Vector Kinematics in Two Dimensions (Motion with Constant Acceleration)

It is expected that students will apply the concepts of motion with constant acceleration to various real-life situations.

B1.  identify situations involving the use of kinematics

B2.  solve problems involving:

•displacement •initial velocity •final velocity •average velocity •acceleration •time

B3.  describe the shape of the path taken by a projectile fired at some angle above the horizon if friction is negligible

B4.  determine from experimental data that the horizontal motion of a projectile is independent of its vertical motion if friction is negligible

B5.  demonstrate that the horizontal velocity of a projectile is constant if friction is ignored

B6.  state that a projectile experiences a constant downward acceleration due to gravity if friction is negligible

B7.  resolve a projectile's velocity into horizontal and vertical components

B8.  solve projectile motion problems involving:

•range •maximum height •time of flight •displacement •velocity •acceleration

PART I - Review of Projectiles Without Angles

• Define projectile motion and give out projectile summary sheet from Physics 11. Explain the use of horizontal and vertal components to solve projectile problems.
• Give out worksheet on Projectile, which is essentially a review of Physics 11 Projectiles. Do question 1 together as a review.

EXERCISE:

• Projectiles worksheet.

 

GUIDED PRACTICE:

PART II - Review of Projectiles With Angles

• Discuss the similarities of solving Projectiles with angles by simply finding the x and y components of the Projectile.
• Go over Example 1 and Example 2 with the class.

• Have students do Example 3 together.

• Give out worksheet on Projectiles with Angles.
