Unit 3 Forces Review

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object in such a way that they cancel each other out, resulting in no change in motion.

Front

What is constant speed?

Back

Constant speed refers to the motion of an object moving at a fixed distance over time, meaning it does not accelerate or decelerate.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to an increase or decrease in speed or a change in direction.

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = F/m, where F is the net force applied to the object and m is its mass.

Front

What is net force?

Back

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

Front

What is the difference between mass and weight?

Back

Weight is the force exerted on an object due to gravity, while mass is the amount of matter in the object, which remains constant regardless of location.

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact, acting parallel to the surfaces.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, meaning it will remain at rest or in uniform motion unless acted upon by an external force.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula: p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, which causes objects to be pulled towards each other, such as objects being pulled towards the Earth.
