TRANSLATIONAL MOTIONS

Chladni figures-making sound visible   The Chladni figures are named after the German scientist Ernst Florens Friedrich Chladni (1756-1827). Chladni excited the normal modes of thin metal plates covered with sand by stroking ... more

Objective: Measurement of instantaneous velocity as a function of distance covered In the case of uniform acceleration, the instantaneous velocity increases as the distance covered becomes greater. The constant of proportionality between ... more

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 ... more

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 ... more

Objective: Determine the acceleration of a falling object. In free fall the distance fallen h is proportional to the square of the time t taken to fall that distance. The coefficient of that proportionality can be used to calculate the acceleration ... more

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 depend on the throwing ... more

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 of ... more

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. This ... more
