Force and Motion

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object does not accelerate; it either remains at rest or continues to move at a constant speed.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a raised object has gravitational potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

How does the position of an object affect its potential and kinetic energy?

Back

As an object moves, its potential energy decreases while its kinetic energy increases, and vice versa, depending on its height and speed.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is when one person pushes a shopping cart while another person pulls it in the opposite direction, causing it to move.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to start moving, stop moving, or change direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is an example of gravitational potential energy?

Back

An example of gravitational potential energy is a book placed on a shelf. The higher the shelf, the more potential energy the book has.
