Force and Motion

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = ma.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate in the direction of the force. It occurs when the net force acting on an object is not zero.

Front

How do you calculate force?

Back

Force can be calculated using the formula F = ma, 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. The greater the mass of an object, the greater its inertia.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, for a given force, an increase in mass will result in a decrease in acceleration.

Front

What is a force?

Back

A force is a push or pull acting upon an object, which can cause it to accelerate, decelerate, or change direction.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the effect of greater acceleration on force?

Back

Greater acceleration results in a greater force required to achieve that acceleration, as described by Newton's second law.

Front

What is balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion of the object.

Front

What is the formula for calculating acceleration?

Back

Acceleration can be calculated using the formula a = F/m, where a is acceleration, F is force, and m is mass.
