Mass And Weight
What is meant by the mass of an object?
A student has a mass of 60 kg. She travels from Earth to a space station orbiting Earth. Which row correctly describes what happens to her mass and weight?
A rock has a mass of 3200 g. Calculate its weight on Earth where g = 9.8 N kg⁻¹.
Which statement correctly describes gravitational field strength?
An object weighs 72 N on Earth where g = 9.8 N kg⁻¹. Calculate the mass of the object.
The gravitational field strength on Earth is approximately 9.8 N kg⁻¹. Which quantity has the same numerical value?
A beam balance is used to measure the mass of a sample on Earth and gives a reading of 4.5 kg. The same balance and sample are taken to the Moon. What reading does the beam balance show on the Moon?
A spring balance (newton meter) reads 50 N when a box is hung from it on Earth (g = 9.8 N kg⁻¹). The same box is hung from the same spring balance on a planet where g = 3.7 N kg⁻¹. What is the reading on the spring balance on this planet?
Two objects are dropped simultaneously from the same height in a vacuum. Object X has a mass of 2 kg and object Y has a mass of 10 kg. Which statement is correct?
A geologist discovers a mineral sample on a planet where g = 4.0 N kg⁻¹. The sample weighs 22 N on this planet. She brings the sample back to Earth where g = 9.8 N kg⁻¹. What is the weight of the sample on Earth?
Which pair of quantities both have the same SI unit?
A student measures the weight of a 400 g object using a spring balance on Earth (g = 9.8 N kg⁻¹). She incorrectly records the mass as 400 kg in her calculation. What weight does she calculate?
A delivery drone carries a 1.5 kg package to the top of a 200 m tall building. Which statement about the package is correct at the top of the building compared to the ground floor?
A satellite orbits a planet at a distance where the gravitational field strength is 2.5 N kg⁻¹. The satellite has a mass of 800 kg. Which statement best describes the weight of the satellite at this location?
On Earth (g = 9.8 N kg⁻¹), an object has a weight of 147 N. The same object is taken to a location where its weight is 24.5 N. Calculate the gravitational field strength at this new location.
