### Episode 207: Projectile Motion

This learning episode, from the Institute of Physics, looks at the independence of vertical and horizontal motion. The crucial concept is that vertical acceleration does not affect horizontal velocity. This explains all projectile motion.

There are a range of activities which include:
• demonstrating...

### Episode 209: Drag, Air Resistance, Terminal Velocity

Produced by the Institute of Physics, this learning episode considers the forces acting on a falling body in air and moves on to related experimental work.

The activities include:
• demonstrating the motion of falling bodies
• understanding upthrust
• investigating air resistance using falling...

### Episode 211: Newton’s Second Law of Motion

Produced by the Institute of Physics, this learning episode explores Newton’s second law, F = ma. Using simple apparatus, students investigate this law and critically consider the limits of the experiment.

The activities include:
• revision of kinematics
• investigating the relationship between...

### Episode 214: Work Done by a Force

In this learning episode from the Institute of Physics, students tackle practical work looking at the efficiency of a ramp to think of force as a mechanism by which energy is transferred from one body to another.

The activities include:
• discussing students' current understanding of force, gravity,...

### Episode 216: Energy Changes

This learning episode, from the Institute of Physics, looks at kinetic energy, work and velocity in relation to the braking distance of a vehicle.

Two experiments are included, both of which connect work done in braking to the initial kinetic energy of the decelerating vehicle.

The activities...

### Episode 218: Mechanical Power

From the Institute of Physics, this resource is concerned with the conservation of mechanical energy and the principle in its wider context.

Produced by the Institute of Physics, this learning episode introduces the concepts of momentum and its conservation.

A series of activities include:
• an introduction to the conservation of momentum
• investigating the conservation of momentum
• application of the conservation of momentum...

### Episode 221: Elastic Collisions

From the Institute of Physics, this learning episode extends the idea of conservation of momentum into elastic collisions, in which, because kinetic energy (KE) is conserved. Useful information can also be found by calculating the changes in KE of the colliding objects.

The activities include:
•...
