What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is calculated as the change in velocity divided by the time taken.

Front

How do you calculate acceleration when given initial and final velocities?

Back

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

Front

What is the formula for calculating net force?

Back

Net force (F_net) is calculated using the formula: F_net = applied force - frictional force.

Front

What happens to gravitational force when the distance between two objects is doubled?

Back

The gravitational force decreases by a factor of 4 when the distance between two objects is doubled, according to the inverse square law.

Front

What is the formula for gravitational force?

Back

The gravitational force (F) between two masses is calculated using the formula: F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

How do you determine the change in velocity?

Back

Change in velocity is determined by subtracting the initial velocity from the final velocity: Change in velocity = final velocity - initial velocity.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, the relationship is given by the formula: F = m * a, where F is force, m is mass, and a is acceleration.

Front

How do you calculate the time taken for an acceleration?

Back

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

Front

What is the significance of a negative acceleration?

Back

Negative acceleration, also known as deceleration, indicates that an object is slowing down.
