Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is calculated as the change in velocity divided by the time taken for that change.

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration.

Front

How do you determine the direction of net force?

Back

The direction of net force is the same as the direction of the acceleration of the object.

Front

What is the formula for calculating net force?

Back

Net force (F_net) can be calculated using the formula: F_net = mass (m) x acceleration (a).

Front

What factors affect the strength of gravity between two objects?

Back

The strength of gravity between two objects depends on their masses and the distance between them.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

If a 10-kg object is subjected to a net force of 50 N, what is its acceleration?

Back

5 m/s² (using the formula a = F/m).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the significance of a positive net force?

Back

A positive net force indicates that an object is accelerating in the direction of the net force.
