Forces and Motion

Front

What is a force?

Back

A force is a push or pull acting upon an object, resulting from its interaction with another object.

Front

What is net force?

Back

Net force is the total force acting on an object when all the individual forces are combined.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = F1 + F2 + ... + Fn, where F1, F2, ..., Fn are the individual forces acting on the object.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a stable surface.

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, acting in the opposite direction to the applied force.

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 the relationship between force, mass, and acceleration?

Back

According to Newton's second law, F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is inertia?

Back

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

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant velocity.

Front

What happens when unbalanced forces act on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
