Force & Motion Assessment

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time. For example, if an object travels 100 m in 20 s, its speed is 100 m / 20 s = 5 m/s.

Front

What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object.

Front

What does Newton's first law of motion state?

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.

Front

What does Newton's second law of motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What does Newton's third law of motion state?

Back

For every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass (Weight = mass × gravity).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is a net force?

Back

The net force is the vector sum of all the forces acting on an object.
