Physics Semester 1 Review

Front

What is the formula to calculate the time it takes for an object to fall from a height under gravity?

Back

t = √(2h/g), where h is the height and g is the acceleration due to gravity.

Front

What is Newton's second law of motion?

Back

F = ma, where F is the net force, m is the mass, and a is the acceleration.

Front

How do you calculate the force acting on an object?

Back

Force (F) is calculated using F = ma, where m is mass and a is acceleration.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

Acceleration is inversely proportional to mass; greater mass results in lower acceleration for the same force.

Front

What is the formula for calculating acceleration?

Back

a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

How do you determine the acceleration of an object given its initial and final velocities?

Back

Use the formula a = (v_f - v_i) / t.

Front

What is the significance of the negative sign in the acceleration due to gravity?

Back

The negative sign indicates that gravity acts downward, towards the center of the Earth.

Front

What is the effect of air resistance on a projectile's motion?

Back

Air resistance opposes the motion of the projectile, reducing its acceleration and range.

Front

How does the mass of an object affect its acceleration when a constant force is applied?

Back

An object with greater mass will experience less acceleration than a lighter object when the same force is applied.

Front

What is the formula for calculating the net force acting on an object?

Back

Net force (F_net) is the sum of all forces acting on an object, F_net = F1 + F2 + ... + Fn.
