G9 Review - Physics

What is the branch of Physics that deals with motion?

What is the third law of motion?

What is the velocity of an object if it is resting?

What is the unit for Work?

Energy is needed to do work. Therefore, the amount of energy needed is equal to the amount of work to be done.

Carbon has 6 protons in it's nucleus. How many neutrons are in its nucleus?

The force needed in order for an object with a mass of 10 Kg to accelerate by 5 m/s₂ is 50N.

What is the branch of Science that explains with how things work?

What is the second law of motion?

It is the contact force which is always in the opposite direction of a moving object.

What is the first law of motion?

It measures how fast an object moves from one point to another.

What is the unit for force?

It measures how strong or how fast an object is.

It is the mass of an object per unit volume?

It is the capacity to do work.

It is the sum of all forces acting on an object.

What is the branch of Physics that deals with the relationship between force and motion?

Helium has an atomic number of 2. What is its atomic mass?

Which equation represents the law of moments?

What is displacement divided by time?

It is the energy in a resting object.

What is the branch of physics that deals with forces?

It is the actual path taken by an object.

What is the turning effect of force?

It is the shortest straight path taken by an object, and is measured from starting point to end point only.

What is the magnitude of a balanced force?

Archimedes principle states that the buoyant force is equal to the weight of the fluid displaced.

In a free falling object, what is the velocity at the moment of impact?

Who is the scientist who wrote the laws of motion?

It is the contact force that prevents a resting object from moving.

It is the strength of the push or the pull on an object.

What is the resultant force with 10 N of force pushes an object while 3 N of force pulls an object?

It is the amount of energy used per unit time.

An object has a weight of 10 N in the air. When fully submerged, its weight is only 6 N. What is the magnitude of F_b?

What is the rate of change of velocity per unit time?

What is the value for acceleration due to Earth's gravity?

It is the transfer of force.

Helium is more dense than Carbon.

It is the exact location of an object in time and space.
