KS3 Physics Springs

What is Hooke's Law?

• Hooke's Law states that the force needed to extend or compress a spring by some distance is proportional to that distance.

• Hooke's Law states that the force needed to extend or compress a spring by some distance is only applicable to certain types of springs.

• Hooke's Law states that the force needed to extend or compress a spring by some distance is unrelated to that distance.

• Hooke's Law states that the force needed to extend or compress a spring by some distance is inversely proportional to that distance.

What is the unit of force ?

• Kilogram (kg)

• Meter (m)

• Second (s)

• Newton (N)

A spring stretches because of the weight. What is the weight of an object?

• The weight of an object is the measure of the force of gravity acting on it.

• The weight of an object is the measure of the force of friction acting on it.

• The weight of an object is the measure of the force of magnetism acting on it.

• The weight of an object is the measure of the force of buoyancy acting on it.

How is weight different from mass?

• Weight is the measure of how much matter is in an object, while mass is the measure of how heavy an object is.

• Weight is the measure of how heavy an object is, while mass is the measure of how much space an object takes up.

• Weight is the measure of how much an object weighs on a scale, while mass is the measure of how much force is exerted on an object.

• Weight is the force exerted on an object due to gravity, while mass is the amount of matter in an object.

What is the formula to calculate weight?

• weight = mass / acceleration due to gravity

• weight = mass * acceleration due to gravity

• weight = mass + acceleration due to gravity

• weight = mass - acceleration due to gravity

A book has a mass of 1kg. What happens to the weight of the book when it is taken to the Moon? the gravitational field strength of the moon is a lot less than the Earth.

• The weight decreases.

• The weight fluctuates.

• The weight remains the same.

• The weight increases.

What is stretching?

• The process of shortening muscles and tendons to improve flexibility and range of motion.

• The process of elongating muscles and tendons to improve flexibility and range of motion.

• The process of strengthening muscles and tendons to improve flexibility and range of motion.

• The process of massaging muscles and tendons to improve flexibility and range of motion.

What is the difference between elastic and inelastic stretching?

• Elastic stretching involves stretching a muscle or tendon beyond its normal range of motion and holding it for a short period of time.

• Inelastic stretching involves stretching a muscle or tendon to its maximum length and holding it for a longer period of time.

• Elastic stretching involves stretching a muscle or tendon to its maximum length and holding it for a longer period of time.

• Elastic stretching involves stretching a muscle or tendon to its maximum length and holding it for a short period of time, while inelastic stretching involves stretching a muscle or tendon beyond its normal range of motion and holding it for a longer period of time.

What is the relationship between force and stretching in a spring?

• Force and stretching in a spring are inversely proportional.

• Stretching in a spring is caused by gravity.

• Force has no effect on stretching in a spring.

• Force and stretching in a spring are directly proportional according to Hooke's Law.

A force can be described as ________

• A push or a pull.
• An up or a down.
• A left or a right.
• Movement.
