If you’re studying physics in school, you may have noticed by now that a lot of memorising is required to succeed, particularly with regards to scientific formulas. Can you recite them all in this quiz? Let’s find out!

• 1.

### Write the formula with:average-speed distance time

Explanation
The formula for average speed is calculated by dividing the distance traveled by the time taken. This formula allows us to determine the average rate at which an object is moving over a given distance and time period. By dividing the distance by the time, we can find the average speed of an object.

### Write the formula with:acceleration change-in-velocity time-taken

Explanation
The formula provided is the equation to calculate acceleration. It states that acceleration is equal to the change in velocity divided by the time taken. This formula is derived from the definition of acceleration, which is the rate at which an object's velocity changes over time. By dividing the change in velocity by the time taken, we can determine how quickly the velocity is changing, thus calculating the acceleration.

### Write the formula with:force mass acceleration

Explanation
The formula for force is given by multiplying mass and acceleration. This formula is derived from Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. Therefore, the correct formula for force is force = mass * acceleration.

• 4.

### Write the formula with:weight mass gravitational-field-strength

Explanation
The formula provided states that weight is equal to the product of mass and gravitational field strength. This formula is derived from the relationship between an object's mass and the force of gravity acting on it. The weight of an object is directly proportional to its mass and the strength of the gravitational field it is in. Therefore, multiplying the mass of an object by the gravitational field strength gives us its weight.

• 5.

### Write the formula with:pressure force area

Explanation
The formula for pressure is given by dividing the force applied on an object by the area over which the force is distributed. This relationship shows that pressure is directly proportional to force and inversely proportional to the area. Therefore, as the force increases, the pressure also increases, while increasing the area over which the force is spread decreases the pressure.

• 6.

### Write the formula with:moment force perpendicular-distance-from-the-pivot

Explanation
The formula provided is the equation to calculate the moment of a force. The moment is equal to the force multiplied by the perpendicular distance from the pivot point. This formula is derived from the principle of moments, which states that the sum of the clockwise moments is equal to the sum of the anticlockwise moments in a balanced system. By multiplying the force by the perpendicular distance, we can determine the rotational effect or moment that the force exerts on the object or system.
