Force and Motion

Front

What is the definition of force in physics?

Back

Force is a push or pull exerted on an object, which can cause it to accelerate, change direction, or change shape.

Front

What are the two main types of forces?

Back

The two main types of forces are contact forces (e.g., friction, tension) and non-contact forces (e.g., gravitational, magnetic).

Front

What is an example of a push?

Back

An example of a push is when you shove a door to open it.

Front

What is an example of a pull?

Back

An example of a pull is when you tug on a rope.

Front

How does the strength of a push affect the motion of an object?

Back

The stronger the push, the faster the object will move; conversely, a weaker push results in slower motion.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity.

Front

What is friction and how does it affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact; it can slow down or stop moving objects.

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 force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not cause a change in motion (net force is zero), while unbalanced forces result in acceleration (net force is not zero).
