Forces and Motion Review

Front

What is the net force?

Back

The net force is the total force acting on an object, taking into account all the individual forces and their directions. It determines the object's acceleration.

Front

According to Newton's Third Law of Motion, what happens when a magnet pulls on an oil drum?

Back

The magnet pulls on the oil drum just as hard as the oil drum pulls on the magnet.

Front

What is an example of a change in motion that produces acceleration?

Back

A ball moving at a constant speed around a circular track.

Front

What can an object that is accelerating be doing?

Back

An object that is accelerating may be slowing down, gaining speed, or changing direction.

Front

What is the unit used to measure force?

Back

The unit to measure force is the Newton.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the object's mass.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.
