Forces Pre Assessment

Front

What is the sum of all forces acting on an object?

Back

Net force

Front

What is Newton's First Law?

Back

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

Front

What is Newton's Second Law?

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 is Newton's Third Law?

Back

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

Front

What type of force causes acceleration?

Back

Unbalanced force

Front

What is tension in physics?

Back

The force exerted by a string, rope, or cable when it is pulled tight.

Front

What is weight?

Back

The force of gravity acting on an object, calculated as mass times the acceleration due to gravity (W=mg).

Front

How do you calculate mass using force and acceleration?

Back

Mass = Force / Acceleration (m = F/a).

Front

What is an example of balanced forces?

Back

Two people pushing a car in opposite directions with equal force.

Front

What happens when forces are balanced?

Back

The object remains at rest or continues to move at a constant velocity.
