GCSE Physics - Vector Diagrams and Resultant Forces #43

The video tutorial explains how to use scale drawings to determine the resultant force on an object. It begins with a scenario involving a cyclist experiencing forces in different directions and demonstrates how to calculate the resultant force using vector addition. The tutorial also covers the concept of equilibrium when forces balance out and introduces the method of resolving vectors into horizontal and vertical components using scale drawings.

What is the resultant force when a cyclist experiences a 4 newton force northwards and a 3 newton force eastwards?

• 6 newtons

• 1 newton

• 7 newtons

• 5 newtons

How do you determine the direction of the resultant force in a scale drawing?

• By measuring the length of the resultant vector

• By using a compass

• By calculating the average of the forces

• By measuring the angle with a protractor

What does it mean when three forces acting on a particle form a perfect triangle?

• The forces are in equilibrium

• The forces are unbalanced

• There is a resultant force

• The forces are parallel

What is the purpose of resolving a vector into its components?

• To change the direction of the force

• To increase the force magnitude

• To split it into horizontal and vertical components

• To find the resultant force

If a 50 newton force is resolved into components on a ramp, what are the horizontal and vertical components if the scale is 10 newtons per centimeter?

• 40 newtons to the right and 30 newtons upwards

• 20 newtons to the right and 50 newtons upwards

• 50 newtons to the right and 0 newtons upwards

• 30 newtons to the right and 40 newtons upwards
