IPC - Semester 1 Exam Review Part I

Front

What is Newton's 2nd Law?

Back

Newton's 2nd Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F=ma).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is the formula for Force?

Back

The formula for Force is F=ma, where F is force, m is mass, and a is acceleration.

Front

What causes a ball to stop rolling?

Back

Friction is the force that causes a ball to stop rolling. It opposes the motion of the ball.

Front

What happens to gravitational strength if the mass of an object decreases?

Back

If the mass of an object decreases, the gravitational strength between that object and another (like the Earth) would decrease.

Front

What is Newton's 1st Law?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is momentum?

Back

Momentum is the quantity of motion an object has, which is dependent on its mass and velocity. It is calculated as momentum = mass x velocity.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, such as the Earth pulling objects towards its center.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, usually measured in kilograms.
