Exploring the different types of force

 

The effect of friction on motion

Force components

Resolving forces 

Newton's First Law.

Tim Peake's Principia mission to the ISS generated some excellent videos that students of all age groups will benefit from. Others in the series include:

1. Principia - Spinning ball on a string then released generates a distance / time graph

2. Principia - Momentum: Small mass into large mass

3. Principia - Momentum: Large mass into small mass

4. Principia - Momentum: Two equal mass head on side view

5. Principia - Momentum: Equal mass inelastic velocity / time graph

Newton's Third Law

This is a video from Veritasium. Other videos from the same source include:

1. Misconceptions about falling objects.
2. The difference between mass and weight

Suport for plotting motion graphs can be found from Science Shorts. This one covers distance-time graphs. 

A similar video for velocity-time graphs can be found here.

SUVAT equations

Circular Motion

There are many other videos in the Hewitt-Drew-it collection

The Monkey and Hunter demonstration of projectile motion

 

Our own IOP Coach, Lewis Matheson, produces some excellent videos on his channel. The playlist on Elasticity includes: 

As well as:

1. Springs in Parallel and Series
2. Energy in Springs
3. Stress, Strain and Young's Modulus
4. Stress-Strain graphs
5. Ductile and Brittle Materials
6. Behaviour of Rubber

 

These experiments have been selected by trained teachers as appropriate for use at home, but we have not specifically tested them for home use.

The following resources are suitable for students aged 11-14 and 14-16:

• Marvin and Milo experiments are useful for teaching younger students. Marvin and Milo explore types of forces in Unbalanced balloons (explores the contact force called tension) and Forceful Comb (explores the non-contact electrostatic force). Newton's Laws are explored in Juice Carton Sprinkler, Slinky drop, Hovercrafty, Spinning Rocket and Head hanger 
• The Royal Institution Rubber Band Cannons can be used as a home based project to explore motion through the air.

Simulations can be useful to generate data in many contexts. 

• An interactive simulation to investigate the law of moments.
• The basic effects of force on motion can be explored using this PhET simulation.
• The interaction of drag and weight can be experimented with using this Physics Classroom simulation - Skydiving
• Othe interactives from Physics Classroom include:
  • Match that Graph
  • Graph that Motion
• Projectile motion simulation can be used to explore the independence of horizontal and vertical motion.
• Hooke's Law interactive simulation. This simulation shows how the force applied to a spring is proportional to the extension of the spring. 

For students aged 14-19:

• Static crate investigates vectors. 
• Coulomb's law interactive simulation. Students can use this to plot a graph to show the factors affecting the strength of the force between two charged objects (16-19 only).
• A similar interactive simulation explores Newton's Law of Gravity.
• Designing a Space Elevator takes students aged 16-19 through a series of material property calculations.
• A number of PhET simulations can be used to investigate simple harmonic motion. These include Masses and Springs and Pendulum Lab.
• Many useful interactives can be found at surendranath.org. Forced, Damped Oscillations is a fun one that can be used to investigate resonance

Health and Safety Guidance

All experiments are carried out at your own risk.

To avoid risk of injury or damage, we recommend that you follow the instructions as shown and that a responsible adult supervises all practical activity and considers the suitability of each task for their child.

Teachers proposing to recommend any resources to their students should:

1. work within safety policies established by their school;
2. use their professional judgement to assess the suitability of experiments for their students;
3. direct students and their parents/guardians to follow all stated instructions.

A selection of diagnostic questions to use remotely when teaching about Forces and Motion

• Best Evidence Science Teaching (BEST) Forces and Motion resource contains a number of questions, along with their respective teaching notes and answers. Some of the individual questions are listed below.

• There are questions from 'Physics for You' by Keith Johnson and our own IOP Coach, Sue Holt. The forces sheet is linked to below.
• Paul Hewitt's 'Next time questions' are a fun way to stimulate thinking about a topic.

For students aged 16-19:

• Teaching Advanced Physics resources feature many question sets to use with your students.
• Question boards on Isaac Physics - A variety of online questions (automatic checking of answers included). They can be accessed without signing up for account, but the free teacher and student accounts allow you to set assignments for your classes. Some examples of the Forces question boards  suitable for 14 - 16 and 16 -19 are given below.
