Grade 10 Physics Extra Practice Booklet Term 3 Finals Given a force, F, acting on a unknown mass, m, causing acceleration a. what equation could be used n to find the value of the mass What is the proportionality constant between force and acceleration? (select one correct answer) Mass Time Velocity Concept 22: Mass remains constant: the same force produces on the same object the same acceleration Anywhere in the Universe, the same net force acting on the same object will always produce the same_________. The mass of an object is always_______ everywhere in the Universe. On Earth, a 100 N force caused a mass m to accelerate by 5 ms^-2. On the moon what force is needed to accelerate m by 5 ms^-2? A man has a mass of 92 kg on Earth. Which of the statements below is correct? (for each one say yes or no) The man's mass on the moon will be 92 kg The man's mass on Mars will be 92 kg The man's mass in space will be 92 kg The man's mass on Mercury will be 92 kg Concept Know that the acceleration of an object is inversely proportional to its mass. How is the acceleration of a body related to its mass? The acceleration of the body is ______ _____ to its mass. Are the mass of a body and the acceleration of a body related? (select one correct answer) No, mass and acceleration have no relation Yes, mass and acceleration are inversely proportional to each other Yes, mass and acceleration are directly proportional to each other State and apply the principle of inertia (Newton's First Law).

Explanation / Answer

19)F=ma

20) a)Mass

21)acceleration

22)constant

23)Since the mass remains constant in the entire universe, to produce same acceleration, same force will be needed .Therefore, answer is 100N

24)a-yes

b - yes

c - yes

d- yes

25)inversely proportional

26) b)Yes, mass and acceleration are inversely proportional to each other

27) A body at rest continues to be at rest or a body in motiuon continues to be in motion unless an external force is applied. This property, by virtue of which the body maintains its state of motion or rest is called inertia
