## What are the 3 equations of motion class 9?

The three equations are, v = u + at. v² = u² + 2as. s = ut + ½at²

## How do you solve force and pressure in Numericals?

1. pressure = thrust.
2. pressure = thrust x area.
3. pressure= thrust /area.
4. pressure = area/thrust.

## What is the second equation of motion class 9?

s = ut + ½ at². It is the expression gives the distance covered by the object moving with uniform acceleration.

## Is physics harder than biology?

Beginning university students in the sciences usually consider biology to be much easier than physics or chemistry. From their experience in high school, physics has math and formulae that must be understood to be applied correctly, but the study of biology relies mainly on memorization.

## Is physics harder than chemistry?

Physics is considered comparatively harder than chemistry and various other disciplines such as psychology, geology, biology, astronomy, computer science, and biochemistry. It is deemed difficult compared to other fields because the variety of abstract concepts and the level of maths in physics is incomparable.

## Is physics harder than calculus?

No, Physics is definitely harder than calculus.

## What is the formula for displacement?

Displacement Formula Displacement = Final position – initial position = change in position.

## What is gufsa?

The purposes of this study are to (a) investigate the effectiveness of using a mnemonic device called GUFSA (Given, Unknown, Formula, Solve, Answer) in math instruction on word problem solving and (b) evaluate the effects of using the SMART board in math instruction for students with LD.

## What are examples of problem-solving?

• Correcting a mistake at work, whether it was made by you or someone else.
• Overcoming a delay at work through problem solving and communication.
• Resolving an issue with a difficult or upset customer.

## What is the 5 step approach?
