Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as \( W = mg \), where \( m \) is mass and \( g \) is the acceleration due to gravity.

Front

What is the formula for centripetal force?

Back

Centripetal force is given by the formula \( F_c = \frac{mv^2}{r} \), where \( m \) is mass, \( v \) is velocity, and \( r \) is the radius of the circular path.

Front

How does gravity affect weight on different celestial bodies?

Back

Weight varies with the gravitational pull of the celestial body. An object's mass remains constant, but its weight decreases on bodies with lower gravity, like the Moon.

Front

What is the definition of velocity?

Back

Velocity is the rate of change of an object's position with respect to time, including direction. It is a vector quantity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time, expressed as \( a = \frac{\Delta v}{\Delta t} \). It can be positive (speeding up) or negative (slowing down).

Front

What does it mean for an object to be in uniform motion?

Back

An object is in uniform motion if it travels equal distances in equal intervals of time, maintaining a constant velocity.

Front

What is the significance of a velocity-time graph?

Back

A velocity-time graph shows how an object's velocity changes over time. The slope represents acceleration, and the area under the curve represents displacement.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.

Front

What happens to an object's motion when it experiences a net force?

Back

An object will accelerate in the direction of the net force according to Newton's second law, \( F = ma \).

Front

What is the concept of inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to mass.
