TRANSLATIONAL MOTIONS

目的:测量瞬时速度和所走距离的函数关系 在加速度一定的条件下，瞬时速度随着所走距离的增加而增加。可以利用速度的平方和所走距离之间的比例常数来计算加速度，这些将会在小车沿着轨道运行的实验中进行测量。为了测量瞬时速度，利用小车上已知宽度的旗帜遮挡光电传感器的光束，光线被遮挡的时间利用数字计数器测量。 更多

Objective: Record and evaluate motion with uniform acceleration on a roller track When uniformly accelerated motion takes place the velocity at any instant is linearly proportional to the time, while the relationship between distance and ... 更多

Objective: Investigate uni-dimensional collisions on an air track One important consequence of Newton’s third law is the conservation of momentum in collisions between two bodies. One way of verifying this is to investigate collisions ... 更多

目标：确定一个下降的对象的加速。 在自由落体运动中，下降的距离和时间是成正比的，实验通过下落距离和时间，可以计算出重力加速度。 更多

Objective: Plotting the “parabolic” trajectories point by point The motion of a ball that is thrown upward at an angle to the horizontal in the earth’s gravitational field follows a parabolic curve whose height and width ... 更多

Objective: Investigate elastic and inelastic collisions between two objects on a plane In any collision between two bodies, the colliding objects must obey the laws of conservation of energy and conservation of momentum. With the help ... 更多

Objective: Confirm the law of equal areas for central force motions (Kepler’s Second Law) As an example of motion under the influence of a central force, the elliptical motion of a pendulum bob is recorded by the dust-marking method ... 更多
