What is Newton's second law of motion?

Back

Newton's second law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

How do you solve for acceleration using Newton's second law?

Back

To solve for acceleration, rearrange the formula to a = F/m, where F is the net force and m is the mass.

If an object has a mass of 5 kg and is in equilibrium, what is the force acting on it?

Back

The force acting on it is 49 N, assuming the acceleration due to gravity is 9.8 m/s² (F = mg).

Front

What is the formula to calculate net force when friction is present?

Back

Net force can be calculated as F_net = F_applied - F_friction.

Front

How do you calculate the net force acting on an object?

Back

Net force is calculated by summing all the forces acting on the object, taking direction into account.

Front

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

Back

The relationship is defined by Newton's second law: F = ma.

Front

If a bicycle accelerates from rest to 4.0 m/s in 8.0 seconds, what is its acceleration?

Back

Acceleration is 0.5 m/s², calculated as (final velocity - initial velocity) / time.

Front

What is the effect of a headwind on the velocity of a moving object?

Back

A headwind reduces the effective velocity of the object relative to the ground.

Front

How do you determine the force exerted by each rope on a hanging object?

Back

Divide the weight of the object by the number of ropes supporting it.

Front

What is the formula for calculating weight?

Back

Weight is calculated as W = mg, where m is mass and g is the acceleration due to gravity.
